Question

a 100m long train,remaining at a speed of 48km/hr passes a tunnel in 21sec l.let's calculate the length of the tunnel.​

Answer 1

GIVEN

INITIAL VELOCITY= 48 KM/ H

IN M/S = 48*5/18 = 13.34m/s

time taken = 21 sec

acceleration = 0

equation = ut + 1/2 at ^ 2

= 13.34* 21 + 1/2*0*21^2

= 13.34 *21

= 280.14 m
