Question

A body starts from rest and accelerates with 4 ms–2 for 5 seconds. Find the distance travelled in 5 seconds.

Answer 1

Distance travelled in 5 seconds = 50 metres

Explanation:

initial velocity u = 0 as the body is at rest

a = 4 ms-2

t = 5

We can get distance traveled from the formula, s = ut + 1/2*at^2

= 0 + 1/2*4*5*5

= 50 metres

Distance traveled in 5 seconds = 50 metres
