15⁰ TT You are on a swing that consists of a seat at the end of a 2.0 m rope. Your friend pulls you back through an angle of 15 degrees and then lets you go to start swinging. As you reach the bottom you scoop up your little sister who was standing on the ground. To what angle does the swing rise after that? Assume your mass is 50.0 kg and your sister's mass is 20.0 kg.

Question
**Problem 2: Swing Physics**

You are seated on a swing that has a seat attached to the end of a 2.0-meter rope. Initially, your friend pulls you back, creating an angle of 15 degrees from the vertical, and then releases you, starting the swinging motion. When you reach the lowest point, you pick up your little sister, who is standing on the ground.

**Objective:**
Determine the angle to which the swing rises after picking up your sister. Assume your mass is 50.0 kg and your sister’s mass is 20.0 kg.

**Diagrams:**
1. The first diagram shows a person seated on a swing at a 15-degree angle from the vertical, ready to start the swing back and forth.
2. The second diagram shows the swing in motion, reaching the vertical position at its lowest point, where the sister is picked up.
3. The third diagram depicts the swing reaching a new angle of elevation (indicated with a question mark) after the sister has been picked up, showing a person with an additional figure (the sister).

**Analysis:**
To solve, apply principles of conservation of energy and physics of pendulums, considering the combined mass and new conditions after picking up the sister.
