Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

### Question:
2. **What would your power output be if you climbed the same stairs in the same amount of time while carrying a stack of books weighing 20 N?**

**Note:**
- The table shows calculations for various physical activities involving climbing stairs. It lists the weight (in Newtons), the height of the stairs, the work done (in Joules), the time taken (in seconds), and the resulting power output (in Watts) for each scenario.
- To solve the question, consider adding the weight of the books (20 N) to your initial weight and calculate the new power output using the same formula for power \( P = \frac{W}{t} \).
