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 88 km/h.

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

(b) Find its displacement at

t = 3.3 s.

(Assume the cheetah maintains a constant acceleration throughout the sprint.)

Step 1

Given data:

Initial speed of the cheetah, u = 0 km/h

Final speed of the cheetah, v = 88 km/h

Distance covered, s = 50 m

Step 2

Writing the third equation of the kinematics:

Step 3

(b)

Let the displacement be s

Writing the se...
