We are asked to find the acceleration of the car:
Formula: s = 1/2 a t^2

20 = 1/2 a (4)^2

a = 40 / 16
a = 5 / 2 m/s^2
= 2.5 m/s^2

The acceleration of the car is 2.5 m/s^2

A car, initially at rest, travels 20 m in 4 s along a straight line with constant acceleration. the acceleration of the car is:
