Thank you for helping me to understanding the concept in working this practice problem out.

Current Attempt in Progress
The drawing shows a collision between two pucks on an air-hockey table. Puck A has a mass of 0.0280 kg and is moving along the x axis
with a velocity of +4.76 m/s. It makes a collision with puck B, which has a mass of 0.0560 kg and is initially at rest. The collision is not
head-on. After the collision, the two pucks fly apart with the angles shown in the drawing. Find the speed of (a) puck A and (b) puck B.

Expert Solution

Step 1: step 1

The image shows a collision between two pucks on an air-hockey table. Puck A has a mass of 0.0280 kg and is moving along the x axis with a velocity of +4.76 m/s. It makes a collision with puck B, which has a mass of 0.0560 kg and is initially at rest. The collision is not head-on. After the collision, the two pucks fly apart with the angles shown in the drawing. Find the speed of (a) puck A and (b) puck B.

To solve this problem, we can use the conservation of momentum and the conservation of kinetic energy. Momentum is conserved in both the x and y directions, while kinetic energy is conserved only if the collision is elastic.

Follow-up Question

It's saying that the answer I'm putting in is incorrect. I also tried the coordinate form but it says invalid.

The image displays two input fields labeled (a) and (b). Each input field consists of:

1. A label indicating "Number."
2. An input box for entering numerical values.
- For (a), the value is "3.36."
- For (b), the value is "1.80."
3. A drop-down menu labeled "Units," with the option "m/s" selected for both (a) and (b).

This layout is typically used for entering data related to velocity, where "m/s" represents meters per second.

No graphs or diagrams are present in the image.
