Question

A body is accelerating at a constant rate of 10 m/s2 . if the body starts from rest, how much distance will it cover in 2 seconds.

Answer 1

u=0
a=10m/s²
t=2 seconds
v=u+at
=0+10×2
=20m/s

Answer 2

Solution: A=10m/s²
               t=2s
               u=0
               v=at=10x2=20
               S=ut+1/2at²
               S=0x2+1/2x10x2²=10x2=20m
               Distance=S=20m
