    Answer:

    16 m

    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:

    s=ut+\frac{1}{2}at^2

    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)

    a=2 m/s^2 is the acceleration

    Substituting t = 4 s, we find the distance covered:

    s=0+\frac{1}{2}(2)(4)^2=16 m
