Question

Transcribed Image Text:**Physics Problem Involving Collision on an Air-Hockey Table**
**Problem Statement:**
The drawing illustrates a collision between two pucks on an air-hockey table. Puck A has a mass of 2.7 kg and moves along the x-axis with a velocity of +5.5 m/s. It collides with puck B, which has a mass of 6.7 kg and is initially at rest. After the collision, the two pucks fly apart at the angles shown in the diagram.
**Diagram Explanation:**
- The diagram shows a top-down view of a collision.
- Before the collision, Puck A (red) moves towards Puck B (blue) at a velocity of +5.5 m/s along the x-axis.
- Puck B is at rest before the collision.
- After the collision, Puck A deflects at an angle of 65° from the direction of initial motion, and Puck B moves at an angle of 37°.
**Questions:**
(a) Calculate the final speed of:
- Puck A: ______ m/s
- Puck B: ______ m/s
(b) Determine the kinetic energy of the A+B system:
- Before the collision: ______ J
- After the collision: ______ J
**Collision Type:**
- Choose the type of collision: elastic, somewhat inelastic, completely inelastic
**Submission:**
- Answer the questions using the information above and submit your answers using the provided form.
