A spring weighing machine inside a stationary lift reads 50 kgf, when a mans stands on it. What would happen to the scale reading, if the lift is moving upward with constant acceleration ?

A man weighs 70 kg. He stands on a weighing scale in a lift which is moving? upwards with a uniform acceleration of 5 ms^-2 .

A man of mass 70 kg stands on a weighing scale in a lift which is moving :- downwards with a uniform acceleration of 5 m s^-2 ,

A man of mass 70 kg stands on a weighing scale in a lift which is moving :- What would be the reading if the lift mechanism failed and it hurtled down freely under gravity ?

A man of mass 70 kg stands on a weighing scale in a lift which is moving :- upwards with a uniform speed of 10 m s^-1 , what would be the reading on scale?

A person normally weighing 50 kg stands on a massless platform which oscillates up and down harmonically at a frequency of 2.0 s^-1 and an amplitude 5.0 cm. A wighing machine on the platform give s the persons weight against time If answer to part is yes, what will be the maximum and minimum reading in the machine and at which position?

A man of mass 70 kg stands on a weighing scale in a lift which is moving :- upwards with a uniform acceleration of 5 m s^-2 . What would be the readings on the scale in each case?

A man weighs 80 kg. He stands on a weighing scale in the lift, which is moving upward with a uniform acceleration of 5 ms^-2 what whould be the reading on the scale? (g = 10 m//s^2) .

A boy standing on a stationary lift (open from above) throws a ball upwards with the maximum initial speed he can, equal to 49 m s^-1 . How much time does the ball take to return to his hands? If the lift starts moving up with a uniform speed of 5 m s^-1 and the boy again throws the ball up with the maximum speed he can, how long does the ball take to return to his hands ?
