How do you find final speed if acceleration time and beginning velocity is given?

You can find the final speed by using the formula: final speed = initial velocity + (acceleration * time). Plug in the given values for initial velocity, acceleration, and time into the formula to calculate the final speed.

How fast is 0.82 mach speed?

Mach 1 at sea level is 340.3 m/s, 761.2 mi/h, 1,225 km/h, so Mach 82 would be 82 times faster.

so Mach 82 is...

27,904.6 m/s

62,418.4 mi/h

100,450 km/h

What is Lami's theorem?

According to Lami's theorem, if a particle under the simultaneous action of three forces is in equilibrium, then each force has a constant ratio with the sine of the angle between the other two forces.

When dropped from this height the kinetic energy when it reaches the ground is equal to if the car was traveling at 100 km h The height from which the 1000 kg car is what?

As long as the mass is the same in both cases, it doesnt enter the calculations.

The height (s) from which to drop it so its velocity at impact is 100 kph (27.78 metres per second):

Use >

s = (v2 - u2) / (2 * a)

s = 771.73 / 19.64

s = 39.29 metres

>

u = 0 (initial velocity - metres per second)

v = 27.78 (final velocity - metres per second)

a = 9.82 (acceleration due to gravity - (m/s)/s)

s = ? (distance - in this case , height)

What is the speed of a car traveling 45 miles in 30 minutes?

To find the speed of the car, you divide the distance traveled by the time taken. In this case, 45 miles divided by 30 minutes equals 1.5 miles per minute. So, the speed of the car is 1.5 miles per minute.

Does the horizontal line on the velocity vs time graph indicate a constant and positive acceleration?

Ahorizontal line on a velocity vs time graph does not indicate any acceleration because there is no slope. Speed remains constant.

Is there a connection between absolute zero and potential and kinetic energy?

Absolute zero is the (theoretical) limit at which all molecular movement stops (that means that the total kinetic energy of all the molecules in the substance being cooled to absolute zero becomes zero).

How fast is asafa Powell mph?

I'm not exactly sure, but since I know that Usain Bolt ran a top speed of 27.9 mph in his 100m world record of 9.58 s, I would guess that Asafa Powel ran maybe 25-26 mph when he ran 9.72 s.

What is the kinetic energy of a 35kg child running at a speed of 1 m's across the yard to tag his friend?

Kinetic Energy = 1/2 * mass * velocity squared

KE = 1/2mV2

KE = 1/2(35 kg)(1 m/s)2

= 18 Joules

How is instantaneous acceleration related to a velocity-time graph?

Acceleration is the derivative of velocity (a=dv/dt). If you are not familiar with calculus then it would be sufficient to say that the slope of the line tangent to the graph, only touches at one point, is equal to the instantaneous acceleration.

When is a body said to possess kinetic energy?

A body is said to possess kinetic energy when it is in motion. Kinetic energy is the energy an object has due to its motion and is dependent on both its mass and velocity.

How fast is mach 4.5 in mph?

'Mach ' is the speed of sound. This depends on air pressure and temperature. On a median day at sea level this is normally 761 mph. That figure can vary if air conditions are changed, but based on this common number, mach 4.5 is 3,324 mph.

How jump is possible in space as there is no reaction force?

I assume you mean micro gravity or in free fall when you write "space" You (the jumper) has to push on something.

Once you have jumped off something you will continue (as Newtons laws of motion propose) until you are stopped by another force.

Where does kinetic energy go after it is used?

If you're suggesting something like an auto accident, the energy of the collision is used to deform materials in the structural elements of the vehicle(s). It also heats them. The primary design features of cars includes a lot of thought to where the energy of a collision can go. Bumpers collapse, body panels and their strengthening members fold and become compressed, and a top or roof can collapse down. All this sinks ("sucks up") energy. And if it all works in an optimal way, you can climb out and walk away.

What is the formula for the total kinetic energy of a moving body?

The formula for the total kinetic energy of a moving body is KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass of the body, and v is the velocity of the body.

How does a gust of wind move dust - dirt - and other particles?

The atoms, molecules, and small particles in air have mass. Wind is the name we give to a moving mass of air. Moving masses possess kenetic energy. Some of this energy can be transfered by collision, to dust, dirt and other particles on the ground, so they are forced to move too. A leaf blower makes use of this principle.

How do you set up the conversion of 35 kilometers per hour to meters per minute?

To convert 35 kilometers per hour to meters per minute, you first need to convert kilometers to meters by multiplying by 1000 (since 1 kilometer is 1000 meters). Then, to convert hours to minutes, you need to multiply by 60. Therefore, 35 kilometers per hour is equal to 583.33 meters per minute.

What are factors that affect an object's kinetic energy?

The factors affecting kinetic energy are mass and velocity.

How fast is 9.5 kph in mph?

9.5 * 1000 * 1000 / 25.4 / 36 / 1760 = 5.903 mph

How does projectile motion compare with Magnus effect?

Projectile motion refers to the motion of an object moving through a gravitational field, such as a ball thrown in the air. The Magnus effect, on the other hand, is a phenomenon where a spinning object experiences a sideways force perpendicular to its direction of motion, affecting its trajectory. In essence, projectile motion is a general term for the motion of objects in a gravitational field, while the Magnus effect is a specific effect caused by rotation.

What is 2 yards per second in mph?

There are 3600 seconds in one hour. Therefore, 2 yards per second is equal to 2 x 3600 = 7200 yards per hour.

There are 1760 yards in one mile. Therefore, 7200 yards per hour is equal to 7200/1760 = 4.09 recurring (that is, 4.090909...) miles per hour.

How does a roller coaster convert potential energy to kinetic energy and then back to potential energy again and again?

So the potential energy is the energy in the car at the top of the first slope.

It changes into kinetic energy (Speed with mass) as it rolls down the hill.

Then the electric motor winds it back up the hill, putting potential energy in the system again.

What can kinetic energy be described as?

The energy a body has because of it motion.
