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

Explanation

To solve the problem step-by-step, we will analyze the situation in each case and use the appropriate formulas to find the readings on the weighing machine.

### Given:
- Mass of the man, \( m = 70 \, \text{kg} \)
- Acceleration due to gravity, \( g \approx 10 \, \text{m/s}^2 \)

### (a) Lift moving upwards with a uniform speed of \( 10 \, \text{m/s} \)
