If the car’s speed decreases at a constant rate from 79 mi/h to 50 mi/h in 3.0 s, what is the magnitude of its acceleration, assuming that it continues to move in a straight line?

In a test run, a certain car accelerates uniformly from zero to 21.6 m/s in 2.15 s. (a) What is the magnitude of the car's acceleration?(b) How long does it take the car to change its speed from 10.8 m/s to 21.6 m/s?

The cheetah can reach a top speed of 114 km/h (71 mi/h). While chasing its prey in a short sprint, a cheetah starts from rest and runs 46 m in a straight line, reaching a final speed of 92 km/h. (a) Determine the cheetah's average acceleration during the short sprint.  m/s2(b) Find its displacement at t = 3.0 s. (Assume the cheetah maintains a constant acceleration throughout the sprint.)

A car starts from rest at t = 0 s, and speeds up with a constant acceleration of 1.81 m/s2 for 6.00 s. Then it continues with a uniform speed for another 6.00 s. Finally, it speeds up with a constant acceleration of 2.02 m/s2 until it reaches a speed of 18.0 m/s. (a) How long does it take for the car to reach a speed of 18.0 m/s? Time is measured from the beginning at t = 0  (b) What is the total displacement of the car?

What is the magnitude of the average acceleration of a skier who, starting from rest, reaches a speed of 11.4 m/s when going down a slope for 3.16 s? (b) How far does the skier travel in this time

An object is subject to a constant acceleration of 4.16 m/s2 in the positive x direction. If it is initially at rest, what is its displacement in the x-direction at t = 8.99 s?

A rocket blasts off and moves straight upward from the launch pad with constant acceleration. After 2.8 seconds the rocket is at a height of 91 meters. (A) What are the magnitude and direction of the rocket's acceleration? (B) What is it's speed at this time? Can you please solve the question using one or more of these equations: v = v0 +at vav = (1/2) times (v0 + v) x = x0 + (1/2) times (v0 + v) times t x = x0 + v0t + (1/2)at2 v2 = v02 + 2a(x - x0)

A train, traveling at a constant speed of 22.0 m/s, comes to an incline with a constant slope. While going up the incline, the train slows down with a constant acceleration of magnitude 1.40 m/s2. (A) What is the speed of the train after 7.20 s on the incline? (B) How far has the train traveled up the incline after 7.20 s?
