Two identical pucks collide elastically on an air hockey table. Puck 1 was originally at rest; puck 2 has an incoming speed of 7.24 m/s and scatters at an angle of 30° with respect to its incoming direction. What is the velocity (magnitude in m/s and direction in degrees counterclockwise from the +x-axis) of puck 1 after the collision? (Assume the +x-axis is to the right.)

Transcribed Image Text:**Title: Elastic Collision of Two Identical Pucks on an Air Hockey Table**
**Problem Statement:**
Two identical pucks collide elastically on an air hockey table. Puck 1 was originally at rest; puck 2 has an incoming speed of 7.24 m/s and scatters at an angle of 30° with respect to its incoming direction. Determine the velocity (magnitude in m/s and direction in degrees counterclockwise from the +x-axis) of puck 1 after the collision. (Assume the +x-axis is to the right.)
**Visual Explanation:**
The diagram shows two pucks:
1. **Puck 1** (red) is initially at rest.
2. **Puck 2** (blue) is moving towards Puck 1 with a velocity of 7.24 m/s from left to right.
Puck 2 scatters at a 30° angle from its initial path after the collision.
- **Final Velocity of Puck 1** (\(\vec{v_1}\)) is shown as a question mark, indicating it's to be calculated.
**Required Calculations:**
- **Magnitude (m/s):**
Fill in the value after solving.
- **Direction (° counterclockwise from the +x-axis):**
Fill in the value after solving.
This problem involves the principles of conservation of momentum and kinetic energy due to the elastic nature of the collision.
