Kinematics

The top speed of a CBR1000 in 1st gear would vary depending on the model year and specific gearing ratios, but typically it would be around 60-80 km/h (37-50 mph). First gear is meant for acceleration rather than top speed.

The wavelength of a macroscopic object like a 300 gram object moving at 100 mph is incredibly small due to its large mass and velocity. To calculate the wavelength using the de Broglie wavelength equation, you would find it to be many orders of magnitude smaller than atoms or subatomic particles due to the classical scale of the object.

For an object with mass m travelling at speed v (assuming it is well below the speed of light), the kinetic energy is given by the mass multiplied by the square of the speed, divided by two. So:

Kinetic energy = m v2 / 2

The potential energy is a little more complicated - this answer assumes you mean gravitational energy. The magnitude of the gravitational potential energy between any two objects is given by the product of their masses multiplied by the gravitational constant, divided by the distance between their centres of mass. Gravity is always an attractive force, so we give it a negative sign to indicate this. So:

Potential energy = - G m1 m2 / r

where G = 6.7 x 10-11 m3 kg-1 s-2

m1 and m2 are the two masses in kilograms (say the mass of the Earth and the mass of the Sun)

r = the distance in metres between their centres of mass

If you need the potential energy in a much simpler example, say by raising an object of mass m by a height h vertically, the solution is much easier. The potential energy then is given by:

Potential energy gained = m g h

i.e. mass (kg) x gravitational field strength (N/kg) x height (m)

On Earth, the gravitational field strength is about 9.8 N/kg Kinetic Energy=1/2 times mass times velocity squared

No, because the amount of force you have applied to the rock cancels with the reaction force from the rock pushing back. Action- reaction. Think about the different types of energy you need to consider:

½mv²

mgh

and possibly rotational ½iω²

Have you given the rock any of these things? If not then there has been no transfer of energy, save possibly the heat from your hands

Potential energy is converted into kinetic energy when an object moves from a higher position to a lower position due to the change in the gravitational forces acting on the object. As the object moves downward, it gains speed and its potential energy decreases while its kinetic energy increases. This conversion follows the law of conservation of energy, where energy is neither created nor destroyed but only changes form.

When the average kinetic energy of a gaseous system is increased, the temperature of the gas increases. This causes the gas molecules to move faster and collide more frequently with the walls of the container, resulting in increased pressure.

At least ten feet thick. This would depend on the weapon used to fire the bullet - an airgun pellet wouldn't require much of a wall, whilst an armour-piercing round from a high-velocity rifle would require a very thick one.

The bifilar suspension experiment is used to determine the unknown moment of inertia of a rigid body. By suspending the object from two different points and measuring the period of oscillation, the moment of inertia can be calculated using the formula for a physical pendulum. This experiment helps verify the parallel axis theorem and provides a practical way to determine moment of inertia experimentally.

The answer to both of your questions lies in the different nature of both quantities, momentum and kinetic energy. Momentum is a vector, kinetic energy is a scalar. This means that momentum has a magnitude and a direction, while kinetic energy just has a magnitude. Consider the following system: 2 balls with equal mass are rolling with the same speed to each other. Magnitude of their velocities is the same, but the directions of their velocities are opposed. What can we say about the total momentum of this system of two balls? The total momentum is the sum of the momentum of each ball. Since masses are equal, magnitudes of velocities are equal, but direction of motion is opposed, the total momentum of the system of two balls equals zero. Conclusion: the system has zero momentum. What can we say about the total kinetic energy of this system? Since the kinetic energy does not take into account the direction of the motion, and since both balls are moving, the kinetic energy of the system will be different from zero and equals to the scalar sum of the kinetic energies of both balls. Conclusion: we have a system with zero momentum, but non-zero kinetic energy. Assume now that we lower the magnitude of the velocity of one of the balls, but keep the direction of motion. The result is that we lower the total kinetic energy of the system, since one of the balls has less kinetic energy than before. When we look to the total momentum of the new system, we observe that the system has gained netto momentum. The momentum of the first ball does not longer neutralize the momentum of the second ball, since the magnitudes of both velocities are not longer equal. Conclusion: the second system has less kinetic energy than the first, but has more momentum. If we go back from system 2 to system 1 we have an example of having more kinetic energy, but less momentum. I hope this answers your question Kjell

In football, potential energy is stored in the ball when it is lifted off the ground before a pass or a kick. When the ball is in motion, it converts this potential energy into kinetic energy. Kinetic energy is what allows the ball to travel through the air and upon impact with a player or the ground.

The collision is elastic because energy will be conserved. The materials don't react with each other (Velcro does not stick to magnets and magnets do not stick/repel velcro) so its no different than two balls hitting each other.

If it was velcro to velcro, and the carts stuck together at the collision, this would be considered an inelastic collision because a lot of Kinetic Energy would be lost.

Regardless of the collision, momentum is always conserved.

if a motion repeats it self after equal intervals of time it is called a periodic motion, if u understand this definition u will know that a fan is undergoing the periodic motion as if of its blades in proper words the blades of an electric fan is a periodic motion

8500 kph (kilometers per hour) = 5,281.655 miles per hour.

There is a multitude of reasons why a food mixer is noisy. First, you can consider the motion of the motor, spinning the "knives" at high speeds, resulting in changes of energy into forms of heat. Secondly, you can consider the food and the mixer colliding with each other.

The potential gradient is a vector quantity. It represents the rate of change of the scalar electric potential with respect to position in space.

Gas exchange surfaces like the alveoli need to be moist because gases, such as oxygen and carbon dioxide, dissolve in water. The thin layer of moisture in the alveoli allows for efficient exchange of gases between the air in the lungs and the bloodstream. This ensures that oxygen can be absorbed into the blood and carbon dioxide can be released from the blood.

It is impossible to tell how far Bruce is going to go out into the lake because the weight for Bruce was not given. KE = 1/2MV squared. KE is Kinetic Energy and M is Mass or Weight while V is Velocity or speed.

It could have kinetic energy when the strings are being pulled and it is in operation

The linear speed will be:

v = 2 * pi * r * f, where

r is circle radius,

f is rotations per second.

To calculate tension, we can use formula for centripetal force, which is:

F = mv2 / r.

This centripetal force will be the tension in the string.

The force required to pull the sled can be calculated using the formula: Force = mass x acceleration. The acceleration due to friction on wet snow depends on factors such as the coefficient of friction and slope of the surface. More information would be needed to provide a specific calculation.

We can easily calculate that deceleration of block is a = v / t = 1.4 / 0.8 = 1.75 m/s2.

The only force acting in the plane of movement may be Ft due to friction.

Formula for Ft is Ft = Q * f, where Q is weight and f is a coefficient of friction.

Q is:

Q = m * g

Ft has also to equal Ft = m * a, so:

m * a = m * g * f

a = g * f

f = a / g

f = v / ( t * g)

For given data, f will be

f = 1.4 / ( 0.8 * 9.81) = 0.178

Distance travelled by bunny is: S = vt

Distance travelled by tortoise in the same time is: S = at2 / 2

Since both times and distances have to be equal, we get:

vt = at2 / 2, which simplifies to:

t = 2v / a

For v = 25 m/s, a = 0.003 m/s2,

t = 16666,67 s or about 4h 38min (different dude) how do you do that tiny little 2 up top?!?!?!)

Strangely worded question. I assume you mean how fast a bike can go. Usually it's more about the rider than the bike, which makes the answer even more muddy. Secondly it's very dependent on what kind of bike and what kind of riding you're talking about, is it on the flat on a fairly normal bike? downhill? alone or in group? for what distance?

Instantaneous speed is the speed of an object at a specific moment in time. It is the rate at which an object is moving at a particular instant. It can be calculated by determining the distance an object has traveled in a very small amount of time.
