Question

A body starting from rest accelerates uniformly at the rate of 2 m/s2 .its velocity after 2 seconds will be​

Answer 1

u=0m/s

a=2m/s^2

t=2s

v=u+at

v=0+2×2=4m/s

Answer 2

Answer:

Given,

Intial velocity U = 0

acceleration, A = 2m/s²

time = 2sec

to find –: Final velocity

according to 1st equation of motion

v = u +at

•> v = 0 +2*2

v = 4 m/s

hence velocity after 2 sec is 4 m/s
