**Physics Practice Problems**

**5.** A 5-kg breadfruit (Ulu) is on a tree 7m above the ground. Relative to the ground, its potential energy is:

- A) 35 J
- B) 50 J
- C) 70 J
- D) 350 J

In the margin, it shows the formula for potential energy: \( PE = mgh \), where \( m \) is mass, \( g \) is acceleration due to gravity (approximately \( 9.8 \, \text{m/s}^2 \)), and \( h \) is height. There's also an annotation: \( g = 9.8 \, \text{m/s}^2 \).

**6.** When using a wrench, a 5 Newton force is applied at a distance of 0.5m. The maximum torque is:

- A) 10 Nm
- B) 5.0 Nm
- C) 2.5 Nm
- D) 0.5 Nm

The text includes a space to indicate where the answers should be recorded.
