Answer:24 m

Explanation:The motion of the car is a uniformly accelerated motion (=at constant acceleration), therefore we can find the distance covered by using the following suvat equation:

where

s is the distance covered

u is the initial velocity

t is the time elapsed

a is the acceleration

For the car in this problem:

u = 0, since the car starts from rest

is the acceleration

t = 4 s is the time elapsed

Therefore, the distance covered is:
