A man of mass 70 kg stands on a weighing machine in a lift, which is moving (a) upwards with a uniform speed of 10ms^(-1) (b) downwards with a uniform acceleration of 5 ms^(-2) (c) upwards with a uniform acceleration of 5 ms^(-2) What would be the readings on the scale in each case ? (d) 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 (a) upwards with a uniform speed of 10 m s^(-1) , (b) downwards with a uniform acceleration of 5 m s^(-2) , (c) upwards with a uniform acceleration of 5 m s^(-2) . What would be the readings on the scale in each case? (d) 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 (a) upwards with a uniform speed of 10 m s 1, (b) downwards with a uniform acceleration of 5 ms^(2) , (c) upwards with a uniform acceleration of 5 ms^(2) . What would be the readings on the scale in each case ? (d) What would be the reading if the lift mechanism failed and it hurtled down freely under gravity ?
