Question
**Scenario: Experimenting with Forces on a Sled**

A child is conducting an experiment to determine whether it is easier to push or pull their sister on a sled. During the test, the child applies force by pushing and pulling at the same angle, as depicted in the illustrations, until motion is achieved.

**Illustration Details:**
- **Left Image:** The child is pushing the sled with his sister sitting on it. The angle of force applied is marked as \( \theta \).
- **Right Image:** The child is pulling the sled using a rope at the same angle \( \theta \).

**Questions to Consider:**
Answer the following questions based on the given conditions:

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

**Problem Statement:**

If the angle is \( \theta = 25^\circ \)

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