Question

a body starts from rest travels with uniform acceleration.if it travels 100m in 5 seconds, what is the value of acceleration?

Answer 1

As we know speed=distance/time
speed=100/5
speed=20 m per sec

Answer 2

s=100m
t=5sec
a=?

v=s/t
a=v/t
=s/t²
a=100/5²
=100/25
=4m/s²

so, the value of acceleration is 4m/s²
