Question

A train starts at a rest and accelerates uniformly at the rate of 5m/s for 5s calculate the velocity of train in 5s

Answer 1

velocity of train after 5 sec =acceleration *time
= 5*5=25m/sec

Answer 2

Initial velocity (u)

final velocity (v)

as the train starts from rest , the initial velocity is 0

acceleration =5m/s²

time = 5 seconds

v=u+at
