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 82 km/h.
(a) Determine the cheetah's average acceleration during the short sprint.
m/s2
(b) Find its displacement at t = 3.4 s. (Assume the cheetah maintains a constant acceleration throughout the sprint.)
m
