A man of mass 60 kg is in a lift and lift is accelerating upwards with acceleration 4 m//s^(2) . Calculate effective weight of man in lift.

A block of mass m is kept on an inclined plane of a lift moving down with acceleration of 2m//s^(2) . What should be the coefficient of friction for the block to move down with constant velocity relative relative to lift?

The mass of a lift if 600kg and it is moving upwards with a uniform acceleration of 2m//s^(2) . Then the tension in the cable of the lift is :

A coin is released inside a lift at a height of 2m from the floor of the lift. The height of the lift is 10 m. The lift is moving with an acceleration of 9 m//s^(2) downwards. The time after which the coin will strike with the lift is : (g=10 m//s^(2))
