Question

A body starts from rest and moves with a uniform acceleration of 2ms^-2 for 8s . The distance travelled by the body during this time interval is

Answer 1

Given

u=0m/s

v=?

s=?

a=2m/s^2

t=8s

From newton's first law

v=u+at

=0+2×8

=16m/s

From newton's second law

s=ut+1/2at^2

s=0×8+1/2×2×8×8

s=64m.
