Question

**Problem Statement:**

A student weighing 311 N climbs a flight of stairs 3 m high in 6 s. What power in watts is required to perform this task?

**Explanation:**

To solve for the power required, you can use the formula for power:

\[ \text{Power} = \frac{\text{Work Done}}{\text{Time}} \]

Where work done is calculated as:

\[ \text{Work Done} = \text{Force} \times \text{Distance} \]

Given:
- Force (weight of the student) = 311 N
- Distance = 3 m
- Time = 6 s

Substitute these values into the formulas to find the power.
