Question

A body starts from rest with a uniform acceleration of 2m/s². Find the velocity of the body after 2s.

Answer 1

Answer:

Given, initial velocity ,u=0m/s

acceleration ,a =2m/s²

time, t =2s

from at+u=v

2×2+0=v

v=4m/s

thus, the velocity of the body after 2sec is 4m/s

Explanation:

we have taken initial velocity 0 because the body has started from rest.
