A man raises a box of mass 50 kg to a height of 2 m 10 s,while another man raises the same box to the same height in 50 s.
(a)Compare :(i)the work done ,and (ii)the power developed by them .
Take g=10 N `kg^(-1)`

Explanation

To solve the problem step by step, we need to calculate the work done by both men and the power developed by each of them.

### Step 1: Calculate the Weight of the Box
The weight of the box can be calculated using the formula:
\[ \text{Weight} = \text{mass} \times g \]
where:
- mass = 50 kg
- g = 10 N/kg (acceleration due to gravity)
