![### Collision of Two Disks
#### Problem Description
Two disks, labeled \( A \) and \( B \), have masses of 4 kg and 6 kg, respectively. They collide with the initial velocities shown in the diagram. The coefficient of restitution for the collision is \( e = 0.75 \). The initial velocities are given as \( (v_{A})_1 = 6 \, \text{m/s} \) for disk \( A \) and \( (v_{B})_1 = 8 \, \text{m/s} \) for disk \( B \).
#### Diagram
The diagram illustrates two disks labeled \( A \) and \( B \), moving towards each other. Disk \( A \) is moving to the right with an initial velocity \( (v_{A})_1 \). Disk \( B \) is moving at an angle of \( 60^\circ \) with respect to the horizontal axis. The line of impact is indicated as the point where the disks come into contact.
### Questions
#### Part A
Determine the magnitude of the velocity of disk \( A \) just after the impact. Provide your answer with three significant figures and include the appropriate units.
\[ (v_{A})_2 = \]
\[ \text{Value} \ \text{Units} \]
#### Part B
Determine the angle between the \( x \)-axis and the velocity of disk \( A \) just after the impact. The angle should be measured clockwise from the negative \( x \)-axis. Express your answer with three significant figures.
\[ \theta_1 = \]
#### Part C
(No additional details provided in the image for Part C)
### Additional Notes
To solve these problems, apply the principles of conservation of momentum and the definition of the coefficient of restitution. Analyze the components of motion along the indicated axes and apply vector analysis to determine the required values.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F98ba27a3-ab69-49b1-ad1c-2aa6f8226754%2F515c0f5c-3ce7-4303-88be-4e1e45b8bf0a%2Fnlmfldx_processed.png&w=3840&q=75)
