A man is standing on the floor of an elevator. The elevator starts coming down with an acceleration ‘a’. What will happen in the following cases :`a = g`.

Consider an elevator moving downwards with an acceleration a, the force exerted by a passenger of mass m in the floor of the elevator is

Find out the expressions of apparent weight of a man in a lift when the lift is coming down with an acceleration (i) a = g and (iii) a gt g.

A lift of mass 200 kg is moving up with an acceleration of 4 m cdot s^(-2) . What is the tension in the lift cable? If the lift moves down with the same acceleration, what will be the tension in that case? [ g = 9.8 m cdot s^(-2) ]

A man of mass 70 kg is sitting in a motor car. The car is moving with an acceleration of 5 m cdot s^(-2) . What is the gravitational force on the man? [ g = 9.8 m cdot s^(-2) ]

A man of mass 98 kg, is standing on a weighing machine in a lift. What will be the readings of the weighing machine in the following cases: (i) the lift ascends at 100 cm per second. (ii) The lift descends with an acceleration of 30 cm cdot s^(-2) ? [ g = 980 cm cdot s^(-2) ]
