Hello!

A car traveling at 25 m/s starts to decelerate steadily. It comes to a complete stop in 8 seconds. What is its acceleration ?

We have the following data:

Vi (initial velocity) = 25 m/s (starts)

Vf (final velocity) = 0 m/s (stop)

t (time) = 8 s

a (acceleration) = ? (in m/s²)

We apply the data to the formula of the hourly function of the velocity, let us see:

The acceleration is -3.125 m/s² (decelerate)
