Cheetahs can accelerate to a speed of 20.2 m/s in 2.65 s and can continue to accelerate to reach a top speed of 29.0 m/s . Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +? direction point in the direction the cheetah runs.Express the cheetah's top speed ?top in miles per hour (mi/h) .Starting from a crouched position, how much time ?accel does it take a cheetah to reach its top speed and what distance ? does it travel in that time?

A motor car is moving with initial velocity in the x-direction at 30 m/s. After 30 s, the car applies its brakes steadily to slow down the car to a velocity of 10 m/s in 12 s. The continues onward for 10 s more. How far in m did the car travel for the full 52 s? Report your answer to three sig figs, you don't need to write "m". HINT: Break up the problem into three stages - 30s, 12s, and the final 10s. During the 12 s, you'll need the acceleration.

A car starts from rest and travels for 10.0 s with a uniform acceleration of +2.0 m/sf. The driver then applies the brakes, causing a uniform acceleration of -1.5 m/s. If the brakes are applied for 1.0 s, determine each of the following. (a) How fast is the car going at the end of the braking period? m/s. (b) How far has the car gone? m Submit Answer
A train starts from station A and for the first kilometer, it travels with a uniform acceleration. Then, for the next two kilometers, it travels with a uniform speed. Finally, the train decelerates uniformly for another kilometer before coming to rest at station B. If the time for the whole journey is six minutes, draw the v-t graph and determine the maximum speed of the train. v (m/s)

Very large accelerations can injure the body, especially if they last for a considerable length of time. One model used to gauge the likelihood of injury is the severity index (??), defined as ??=?^5/2?. In the expression, ?t is the duration of the acceleration, but ?a is not equal to the acceleration. Rather, ?a is a dimensionless constant that equals the number of multiples of ?g that the acceleration is equal to. In one set of studies of rear-end collisions, a person's velocity increases by 17.5 km/h17.5 km/h with an acceleration of 30.5 m/s230.5 m/s2 . Let the +?+x direction point in the direction the car is traveling. What is the severity index for the collision? How far ?d does the person travel during the collision if the car was initially moving forward at 4.60 km/h4.60 km/h ?
A bus initially at a bus stop accelerates continuously for a kilometer, taking a minute and a half. Upon closing in on the next stop, the driver then begins to hit the brakes until it reaches a full stop in 8 seconds. Find the total distance that the bus traveled and the velocity of the bus just before it begins decelerating.
