Question

Cheetahs can accelerate to a speed of 20.0 m/s in 2.50 s and can continue to accelerate to reach a top speed of 29.5 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).
top=
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?

accel=
s
=
m
If a cheetah sees a rabbit 131.0 m away, how much time total will it take to reach the rabbit, assuming the rabbit does not move and the cheetah starts from rest?

total=
