Question

How far will a body move in 4 seconds if uniformly accelerated from rest at the rate of 2m/s square​

Answer 1

16m

Step-by-step 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 +
`(1)/(2)` at²

s is the distance

u is the initial velocity

t is the time

a is the acceleration

s = (0 x 4) + (
`(1)/(2)` x 2 x 4²) = 16m
