An elevator is accelerating vertically upwards at . A man of mass is standing inside. Determine the reaction force of the floor on the man.
An elevator was accelerating vertically downwards at 1.7 m/s2. Given that the acceleration due to gravity is , find the reaction force of the floor to a passenger of mass 103 kg.
An elevator is moving vertically upwards at a constant speed. A man of mass 150 kg is standing inside. Determine the reaction force of the floor on the man. Take .
A body of mass 4 kg is hanging from a spring balance fixed to the ceiling of a lift. Given that the reading on the balance is 1 042 g-wt, determine the magnitude of the acceleration of the lift. Take .
A lift is ascending with an acceleration of 140 cm/s2. Given that a person standing inside the lift is exerting a force of 106 kg-wt on the floor, find his mass. Take .
