Two parallel rail tracks run north-south. Train A moves north with a speed of `54 km h^(-1)`. What is the
(a) velocity of B with respect to A ?
(b) velocity of ground with respect to B? and
(c) velocity of a monkey running on the roof of the train A aginst its motion (with a velocity of `18 km h^(-1)` with respect to the train A) as observed by a man standing on the ground ?

Two parallel rail tracks run north-south. Train A moves north with a speed of 54 km h^(-1) , and train B moves south with a speed of 90 km h^(-1) . What is the (a) velocity of B with respect to A ?, (b) velocity of ground with respect to B ?, and (c) velocity of a monkey running on the roof of the train A against its motion (with a velocity of 18 km h^(-1) with respect to the train A) as observed by a man standing on the ground ?

Two parallel rail tracks are in north-south direction. Train A moves towards north with a speed of 72 kmh^(-1) and train B moves towards south with a speed of 108 kmh^(-1) What is the (a) velocity of B with respect to A ?, (b) velocity of ground with respect to B ? and (c) velocity of a monkey running on the roof of the train A against its motion (with a velocity of 27 kmh^(-1) with respect to the train A) as observed by a man standing on the ground?
