A train moves in north direction with a speed of 54 km/hr. and a monkey running on the roof of the train, against its motion with a velocity of 18km/hr. with respect to the train, then the velocity of monkey as observed by a man standing on the ground:-

Two paarallel 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. relative velocity of B with respect to A ? b. relaity of a monkey running on the roof of the train A against its motion (with its velocity of 18 km h^(1) with respect ot the train A ) as observed by a man standing on the fround?

A man is sitting in a train which is moving with a velocity of 60 km/hour. His speed with respect to the train is:

A train is moving towards East with a speed 20 m/s. A person is running on the roof of the train with a speed 3 m/s against the motion of train. Velocity of the person as seen by an observer on ground will be :

A train 200 metres long, running with a speed of 30km/hr. will pass a standing man in.

The speed of train is 54km/hr. Find it in m/s

A train 100m in length, is moving with a velocity of 54km/hr in one direction, Another train, 80m in length, is moving with a velocity of 36km/hr in the opposite direction. Find the time when the two trains will completely cross each other.

A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train?

A bird is flying with a speed of 40 km/hr. in the north direction. A train is moving with a speed of 40km/hr. in the west direction. A passenger sitting in the train will see the bird moving with velocity:-
