Question

A cheetah can accelerate from rest to a speed of 28.0 28.0 m/s in 3.50 3.50 s. What is its acceleration?

Answer 1

Answer:8m/s²

Explanation:

Acceleration of a body is defined as the change in velocity of a body with respect to time. Mathematically,

Acceleration = change in velocity/time

= final velocity - initial velocity/time

Since cheetah accelerates from rest, its initial velocity is 0m/s

Final velocity = 28.0m/s

Time = 3.50s

Acceleration = 28-0/3.5

Acceleration = 8.0m/s²
