Question

A train travelling at a speed of 48 km/h takes 27 seconds to cross a man standing on a railway platform find the length of the train hence find the time taken by the train to cross a bridge 2.64 km long

Answer 1

Answer:

the man requires 27 seconds to cross railway station

we can apply newton's three equation of motion here:-

to find acceleration

a=13.3333/27=0.5 m/s^2

now

s=ut+1/2at^2

s=13.3333×27+1/2×0.5×27^2

s=360+182.25

s=542.25 m

length of train is 542.25 m

now time to travel 2.64 km

s=ut+1/2at^2 apply the equation and find the time required try this one urself
