Answer:8m/s²
Step-by-step 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
