Question

A train of length 100m starts from rest with constant acceleration 10m per second square.if train starts to cross an electric pole from rest ,the velocity of the train when mid point is crossing the electric pole is

Answer 1

• u=o
• s=100 m
• mid point = 50 m

a = 10 m/s²

now , we have

2as= v²-u²

v²- 0 = 2as

v²= 2as

v²= 2×10×50

v= √1000 m/s²

v =10√10 m/s
