Question

on two parallel railway tracks train A and train B are moving in opposite direction , if train A moves at 45 kmh and train B moves at 70kmh . Calculate the relative speed of (a) train B w.r.t A (b) train A w.r.t train B , (c) ground w.r.t A​​

Answer 1

Answer:

Two parallel rail tracks run north-south. Train A moves north with a speed of 54 kmh

−1

and train B moves south with a speed of 90 kmh

−1

, What is the

a. the relative velocity of B with respect to A?

b. the relative velocity of the ground with respect to B?

c. a velocity of a monkey running on the roof of the train A against its motion (with its velocity of 18 kmh−1 with respect to the train A) as observed by a man standing on the
