Question
### Experiment: Pushing vs. Pulling on a Sled

A kid is testing whether it is easier to push or pull their sister on a sled. During the test, they push and pull their sister at the same angle, as shown in the picture, until she moves.

#### Diagram Explanation

The diagram shows two scenarios:

1. **Pushing a Sled:** The kid is behind the sled, applying force in a downward direction at an angle \(\theta\).
2. **Pulling a Sled:** The kid is in front of the sled, applying force in an upward direction at the same angle \(\theta\).

Both scenarios illustrate the direction of the force applied by the kid and the resulting angle of application.

#### Questions to Consider

Answer the following questions, given that:

- The friction force \( f = 0.1 \times \text{Normal Force} \)
- The combined mass of the sled and sister \( m = 50 \, \text{kg} \)

Explore how the angle and direction of force application affect the ease of moving the sled.

If the angle is \( \theta = 18 \)

What is the force needed (in Newtons) to get the sled to move when the kid pushes?
