What is an object's acceleration if it is moving at 40 m/s and comes to a stop in 5 s?

Sagot :

An object's acceleration if it is moving and comes to a stop in 5 s will be  8 m/s².

What is acceleration?

Acceleration is defined as the rate change of velocity with time.

acceleration a = (Δv) / (Δt)

An object is moving with initial velocity u = 40 m/s and it comes to stop, then its final velocity  v= 0 m/s.

Time taken for the change in speed t=5s.

The acceleration is given by

a = (40 -0)/ 5

a = 8 m/s²

Thus, the object's acceleration is  8 m/s².
