Respuesta :
When any object changes its velocity with time, the object is said to be having accelerated motion. The cheetah's acceleration is 8.9 m/s² .
What is acceleration?
Acceleration is the time rate of change of velocity.
Acceleration is represented by
a = v-u / Δt
where, v is the final velocity, u is the initial velocity and Δt is the time interval.
Cheetah starts at rest (0 m/s) and final velocity is 26.7 m/s. It took 3 seconds for the cheetah to reach this speed. Then , the acceleration is
a = 26.7 -0 / 3
a = 8.9 m/s²
The cheetah's acceleration is 8.9 m/s²
