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 50 m in a straight line, reaching a final speed of 89 km/h.

Question

(a) Determine the cheetah's average acceleration during the short sprint.
m/s2

(b) Find its displacement at
t = 3.2 s.
(Assume the cheetah maintains a constant acceleration throughout the sprint.)
m

Answer 1

First, convert km/hr to m/s
(a)v^2 = 2as
(b) s = 1/2 at^2
