### Problem Statement

1. A mass of **500 kg** sits on a level surface where the coefficient of static friction is **0.5**. What is the minimum force applied at **60° up** from the horizontal needed to start the mass moving?

### Explanation

- **Mass**: 500 kg
- **Coefficient of Static Friction**: 0.5
- **Angle of Applied Force**: 60° from the horizontal

The problem involves calculating the force necessary to overcome static friction and initiate motion in the mass. The force is applied at an angle, which affects the horizontal and vertical components of the applied force.
