Question

A body is moving with uniform acceleration of 10 m/s². If it starts from rest, calculate its displacement after 5 S.

Answer 1

S = 0.5at^2
S = 0.5*10*5^2
S = 125m

Displacement after 5s is 125m

Answer 2

s=ut+1/2at^2
u=0, a=10m/s^2, t=5
Therefore, s= 0x5+ 1/2 x 10 x 5 x 5
or, s= (5 x 5 x 5) m= 125m
