Homework Statement

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 85 km/h.

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

(b) Find its displacement at
t = 3.0 s.
(Assume the cheetah maintains a constant acceleration throughout the sprint.)

The Attempt at a Solution

I've been using a velocity calculator but still getting the wrong answer and honestly i just don't know what I'm doing
