Question

A body starting from rest travels with uniform acceleration. If it travels 125m in 10 sec then its acceleration is ____________

Answer 1

a body is at rest ,  so  u [initial velocity =0]=0

final velocity is 125 m

velocity v = final - initial velocity = 125- 0= 125

time=10 sec

and  acceleration = v/t = 125 m /10 sec= 12.5 metre / sec
