(a) Determine the cheetahs 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.) ___m-(a).(71/3.......
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 71 km/h.
(a) Determine the cheetah's average acceleration during the short sprint.
___ m/s2

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

-
(a).

V² = v² + 2 as

(71/3.6)² = 0² + 2 a(50)

a = 3.88966 m/s²




(b).

s = ½ a t²

s = ½ (3.88966)(3)²

s = 17.50347 meters
