Explanation:
For an object in uniformly accelerated motion (=with constant acceleration), the distance covered by the body can be found by using the following suvat equation:
where
s is the distance covered
u is the initial velocity
t is the time
a is the acceleration
For the body in this problem,
u = 0 (it starts from rest)
is the acceleration
Substituting t = 4 s, we find the distance covered:
