Question

A car starts from rest at a stoplight and reaches 20 M/s in 3.5 seconds determine the acceleration of the car

Answer 1

`a = (v)/(t)`
so just plug in the velocity for v, which is 20 m/s
and plug in the time for seconds which is 3.5s

so

`a = (20 (m)/(s) )/(3.5s)`
that will give you your answer
