Two identical pucks collide elastically on an air hockey table. Puck 1 was originally at rest; puck 2 has an incoming speed of 5.30 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:**Collision of Pucks on an Air Hockey Table**
Two identical pucks collide elastically on an air hockey table. Puck 1 was originally at rest; puck 2 has an incoming speed of 5.30 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.)
**Diagram Explanation:**
- The diagram shows two pucks: a red puck (puck 1) initially at rest and a blue puck (puck 2) approaching it from the left.
- Puck 2 is moving with an initial speed of 5.30 m/s.
- After collision, puck 2 scatters at a 30° angle from its original path.
- The velocity vector for puck 1 (`v₁`) is unknown and represented with a question mark.
**Solution:**
- Attempted values:
- Magnitude: 3.00 m/s (incorrect)
- Direction: 60° counterclockwise from the +x-axis (incorrect)
The diagram uses color-coded vectors and angle annotations to illustrate the scenario and the problem.
