54 km per second is equal to 120,794.56 mph
As the material body travels at the speed of light its relativisticmass becomes infinite. Hence the kinetic energy too becomesinfinite which is not practically possible
Scalar because you give only the distance, not direction as well.It would also be scalar if you had quoted only the speed (notvelocity), for the same reason. A vector has magnitude anddirection.
With poor language we cannot assess. Any way the objects speed goeson increasing
Simple harmonic motion is understood from an oscillating pendulum.It is also periodic. An example of periodic motion without simpleharmonic motion is the rotation of the blades of a fan.
The specific heat capacity of motor oil is 2 Kj/ Kg. That means 2kilojoules and kilograms which is how heat is measured.
A turbine or a windmill converts wind motion into energy. Note thatit actually has to intercept/stop the motion to do this. If youcould build a perfect windmill, the air would perfectly calm on theother side of that windmill.
The rate constant is something that must be solved for in eachindividual equation. Without more information, it is impossible toanswer the question completely.
I posted this earlier. weather the van is in gear or out of gear, driving or braking, as soon as it pass 50 mph it starts to make clunking noises from under the engine. not particular to one particular place but mostly from under the passenger footwell, then under the engine itself and sometimes a...
Average acceleration during the time interval = (change on speed) / (time for the change) = (98 - 121) / (12) = -23/12 = negative (1 and 11/12) meters per second 2

In an elastic collision between two objects do both objects have the same kinetic energy after the collision as before? Let's do the problem and see The problem below will prove that in an elastic collision between two objects the objects do not have the same kinetic energy after the...
To convert from miles to kilometers, you multiply by 1.6. Samething, to convert from miles per hour to kilometers per hour.
30,000 feet per hour = 5.68 miles per hour.
1) Work input = Force * distance 2) Force = mass*acceleration 3) Acceleration = (Vf - Vi) Ã· time 4) Force = mass * [(Vf - Vi) Ã· time] 5) Distance = Average velocity * time 6) Average velocity = (Vf + Vi) Ã· 2 7) Distance = [(Vf + Vi) Ã· 2] * time Eq#4 * EQ #7 8) Work input =...
Final velocity = Initial velocity +(acceleration * time)
Vf = Vi + at Where Vf = final velocity Vi = initial velocity a = acceleration t = time
Momentum is the product of the mass and the velocity of an object. It's SI unit is kgms -1 . Correct, but perhaps more easily interpreted as kgm/s.
The slope of a time-distance chart would be a constant. The slope of a time-velocity chart would be 0.
When speed decreases, kinetic energy must alslo decrease.
In an isolated system the total momentum of a system remainsconserved. For example If you fire a bullet from Gun , bullet goforward with some linear momentum and in order to conserve thelinear momentum the gun recoils
Relationship between work and kinetic energy. Work is defined as the result of a force moving an object a distance and is stated by the equation W=Fd. But the result of the force being applied on the object also means that the object is moving with some given velocity, according to the equation for...
Yes the kinetic energy of solid increases resulting in increase ofvibration of atoms in their mean positions
I am assuming the initial speed is 6.2 m/s Let upward motion be positive! Gravity decreases the speed by 9.8 m/s each second Acceleration due to gravity = -9.8 m/s each second (negative because gravity accelerates objects downward) Find time to reach the top of the path! Final velocity at...
The truck needs 400 feet to stop

depends on the speeds and weights of the involved vehicles.
mgh = 10 x 10 x 10 = 1000 J ( Assume g value as 10 m/s 2
Kinetic energy is energy from motion, so if an apple is moving, then it has kinetic energy. If not, then it does not.
Riding a bike down a hill. You gain potential energy on the way up, but on the way down you lose that potential energy and gain an equal amount of kinetic energy.
About 5 minutes 21 seconds at that rate of travel.
Is this a question? or a statement that you are unsure of? Well anyways, this would be correct if acceleration was a constant but if acceleration is not a constant, the (not-constant) acceleration would change the rate of velocity and thus that statement/question would be false.
Correct and easier way: Kinetic friction is just a part of magnitude of forces affecting an object, so it can be multiplied by g(9.81) to get the total acceleration essentially. Coefficient(.3)=F(friction)/F(normal) So multiply .3 by g(9.81) to get 2.943 -2.943 is the acceleration of the object,...
And what is the question? And what is the question? And what is the question? And what is the question?
Kinetic energy because kinetic energy is the energy a body possesses by virtue of its state of motion but potential energy is the energy a body stores by virtue of its state or position.
Kinetic energy is the movement of molecules through a time constrained gradient. Since time flows unevenly through most mediums, it makes it virtually impossible for a super cell to maintain the resistance necessary to store this energy in its' passive state. However, the work done by the kinetic...
Temperature is the measure of average kinetic energy of all theatoms and molecules in an object
The sum of potential and kinetic energy gives you the MechanicalEnergy of the system
Both mass and velocity impact energy the same. Newtons second law states that Energy is the time derivative of the product on mass and velocity
Thermodynamic average energy of ideal gas in 3D is 3/2k B T. k B is the Boltzman constant, and T is the temperature in Kelvin. .
If both are travelling at the same speed, certainly the bowling ball has much more kinetic energy, as it is, simply put, heavier. otherwise, Wk = m*v 2 /2
The fastest recorded so far is Usain Bolt at 27.44 miles per hour.
-- Measure the force you use to pull the object. You can connect a spring "fish" scale to the object, pull on the scale, and read off the force while the object moves. -- Measure the distance the object moves. Multiply the force by the distance. The product is the energy used to move it. ...
A horizontal line on a distance-time graph means the object is at rest.
Non. Light is electromagnetic radiation and travels at a constant velocity c in vacuum, no matter the velocity of your observation point. c = 2.9979 x 10exp5 km/sec.
12 mph equates to 352 yards per minute.

Kinetic energy = 1/2 * mass * speed^2 When mass decreases, kinetic energy decreases proportionally.
We use energy that has been in existence, in some form, since the beginning of the Universe. .
Actually, humans do "create" energy. We use a chemical process to break down various food molecules, releasing the bonding energy which formerly held such molecules together.
Approximately 4,152,611.08 mph
the slope of static friction & normal force represents "coefficient of friction' which is constant for a particular surface
yes. For ex. Gravitational potential energy is caused by height.
it was created by "analysis of Newton's Laws using calculus"
A vector having both magnitude and direction

Vector quantities have both magnitude and direction I think u can also look it up on Google for a more in depth answer but this is basicaly right Yeaya Whos da bomb ....not you!
The questions in H C Verma are a bit conceptual in nature. Study the book thoroughly first and then try the in-text questions. After that even if you find it difficult to solve. Study other books like Mtg Interactive Physics, Ncert, Fundamentals of physics. I hope after that you will be able to...
Falling off a cliff, or a duck could fly threw your window and stab you.
The black bird speed is 678.98 miles an hour
Simple Answer: Mass and inertia are essentially the same thing. Better Answer: Inertia is a characteristic of any physical object and mass is the quantitative measure of the characteristic. This is embodied in Newton's first law of motion. We can say this as follows. An object in...
The object's kinetic energy is 78.4 joules.
i watch my superman fly away
For any object, the summation of its potential and kinetic energies is constant.
Yes. The graph indicates that the position does not change while the time is changing - ie the object is not moving.
4/5 of an hour = 12 minutes
0 because initial is your starting point and the ball hasn't been thrown yet
40 Joules. This would also mean that the ideal included zero mass or elasticity in the "string" of the bow, friction is non-existent, and it is accomplished in a vacuum.
Increase the object's speed, or its mass, or both. answer2: Increase the momentum by a Force impulse, Fdt= dP. (The effect of that is to increase the object's speed.)
Potential energy = m g h = (8 x 10 6 ) (9.8) (50) = 3.92 x 10 9 joules

From the information given, we don't really know. We know that the acceleration vector points to the right, but the velocity could be anywhere.
They can be used for measuring speed of any object.
KE = (1/2)mv 2 where m = mass (in kilograms), and v = velocity (in meters/second) this gives you the kinetic energy in units of Joules
Scalar and vector quantities give magnitude , and that makes them similar. The difference is that the vector quantity gives direction as well as magnitude.
If the velocity begins at v it steadily decreases to zero. It continues to decrease until (neglecting air resistance) it reaches -v and hits the ground. The acceleration is constant at -9.81 m/s/s.
150 miles per hour. (600/4 = 150)
It is the force constant of the material in N/m. So you can substitute it into the equation F=kx (F=force, k=force constant or gradient in N/m, x = extension) You would expect the extension to be on the y-axis normally since it is the measured value. However since you want to use the graph to...
Kinetic energy. Specifically K.E. = Â½mvÂ² where K.E. is kinetic energy m is mass v is velocity
