The cheetah can reach a top speed of 114 kmh 71 mih while, Ask an Expert

Academics

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 89 km/h.

(a) Determine the cheetah's average acceleration during the short sprint.

(b) Find its displacement at t = 3.1 s. (Assume the cheetah maintains a constant acceleration throughout the sprint.)
