Question

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

Answer 1

acceleration=rate of change of velocity=v-u/t
u[initial velocity]=0
s=ut+1/2at^2
100=0+1/2*a.5*5
100=25/2 *a
a=8m/s^2

Answer 2

u=0
s=100
t=5
s=ut+1/2 at²
100=0X5+1/2Xa[25]
100=25a/2
a=8 m/s²
