A man weighs 70kg. He stands on a weighting machine in a lift, which is moving (a) Upwards with a uniform speed of 10m/s. (b) Downwards with a uniform acceleration of 5m/s^2. (c) Upwards with a uniform acceleration of 5m/s^2. Take g = 9.8m/s^2. What would be the readings on the scales in each case what would be the reading if the lift mechanism failed and it came down freely under gravity?
