. The cheetah is the fastest running animal in the world. Cheetahs can accelerate to a speed of 20 m/s in 2.5 an can continue to accelerate to reach a stop speed of 29 m/s. Assume the acceleration is constant until the stop speed is reached and is zero thereafter.

(a) Express the cheetah's top speed in miles per hour.

(b) starting from a crouched position, how long does it take a cheetah to reach its top speed and how far does it travel in time?

(c) If a cheetah sees a warthog 120 m away how long will it take to reach lunch assuming the warthog does not move?
