An object is moving with a speed 100 m/s. Find the distance travelled by this object in one minute

A man is 25 m behind a bus, when bus starts accelerating at 2 ms^(-2) and man starts moving with constant velocity of 10 ms^(-1) . Time taken by him to board the bus is

A man weighing 60 kg is in a lift moving down with an acceleration of 1.8" ms"^(-2) . The force exerted by the floor on him is

When Rahul walks up a stationary escalator,then he takes 20s to reach the top.While when he walks up a moving escalator,he takes 10s to reach the top.The time taken by him to reach the top when stand still on the moving escalator is?

A 90-kg man runs up an escalator while it is not in operation in 10s . What is the average power developed by the man. Suppose the escalator is running so that the escalator steps move at a speed of 0.5m^-1 . What is then the power developed by the man as seen by the ground reference if he moves at the same speed relative to the escalator steps as he did when the escalator is not in operation?

A man moving with 5 ms^-1 observes rain falling vertically at the rate of 10 m s^-1 . Find the speed and direction of the rain with respect to ground.

An elevator, in which a man is standing, is moving upward with a constant acceleration of 2 m//s^2 . At some instant when speed of elevator is 10 m//s , the man drops a coin from a height of 1.5 m . Find the time taken by the coin to reach the floor.

A man walks for 1 "minute" at a speed of 1 m s^(-1) and then runs for 1 min at a speed of 3 ms ^(-1) along straight track, What is the average speed of the man?
