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?

1.	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?
Answer» Solution :(a)`-50 ms ^(-1),` (B) VELOCITY of B w.r.t. GROUND `= 30 ms ^(-1),` (c ) Velocity of monkey `= 12.5 ms ^(-1)`
