**Problem Description:**A 35-kg child starts at rest at the top of a slide and exits at a speed of 6.0 m/s. The slide has a height of 3 meters. The task is to determine how much work was done by friction as the child descends the slide.**Diagram Explanation:**The diagram shows a curvy slide with the child positioned at the top, 3 meters above the ground. It depicts the path a child would take going down the slide, starting from rest and accelerating due to gravity.**Question:**What is the work done by friction?**Answer Options:**- -400 J- 400 J- Cannot determine from information given- 0- -225 J- 225 J**Understanding the Problem:**To solve this, apply the principles of energy conservation. Initially, the child has potential energy and no kinetic energy. At the bottom, the child has kinetic energy. The difference in energy can help determine the work done by friction.

Question

**Problem Description:**

A 35-kg child starts at rest at the top of a slide and exits at a speed of 6.0 m/s. The slide has a height of 3 meters. The task is to determine how much work was done by friction as the child descends the slide.

**Diagram Explanation:**

The diagram shows a curvy slide with the child positioned at the top, 3 meters above the ground. It depicts the path a child would take going down the slide, starting from rest and accelerating due to gravity.

**Question:**

What is the work done by friction?

**Answer Options:**

- -400 J
- 400 J
- Cannot determine from information given
- 0
- -225 J
- 225 J

**Understanding the Problem:**

To solve this, apply the principles of energy conservation. Initially, the child has potential energy and no kinetic energy. At the bottom, the child has kinetic energy. The difference in energy can help determine the work done by friction.
