Answer:

16m

Explanation:

Given parameters:

Time  = 4s

Initial velocity  = 0m/s

Acceleration  = 2m/s²

Unknown:

How far will the body move  = ?

Solution:

To solve this problem, we use the expression below:

  s  = ut  + [tex]\frac{1}{2}[/tex] at²  

s is the distance

u is the initial velocity

t is the time

a is the acceleration

 

   s  = (0 x 4) + ( [tex]\frac{1}{2}[/tex] x 2 x 4²)  = 16m
