The leaning tower of Pisa is 45 m high. A mass of 4 kg is drow from the. top Calculate its potential eneigy at the top

Explanation

To calculate the potential energy of a mass at a certain height, we can use the formula for gravitational potential energy:

**Potential Energy (PE) = m * g * h**

Where:
- **m** = mass (in kilograms)
- **g** = acceleration due to gravity (approximately 9.8 m/s²)
- **h** = height (in meters)
