One coolie takes 1min to raise a box through a height of `2m`. Another one takes `30s` for the same job and does the same amount of work. Which one of the two has greater power and which one uses greater enegy?

Explanation

To solve the problem, we need to analyze the work done by both coolies, the time taken, and then calculate the power for each coolie.

### Step-by-Step Solution:

1. **Understanding Work Done**:
- Both coolies are lifting the same box through the same height (2 m).
- The work done against gravity is given by the formula:
\[
