Your answer must include 3 places after the decimal point, and proper SI unit.**Diagram Explanation:**- **Diagram Overview:** The diagram shows two disks, A and B, colliding. Disk A is labeled with an initial velocity \( v_{A,1} \) pointing downward along the y-axis. Disk B’s initial velocity \( v_{B,1} \) is perpendicular to disk A’s velocity, pointing to the left along the x-axis. - **Angle and Lines:** The collision plane forms a right triangle with the adjacent and opposite sides to the velocity vectors labeled as 3 and 4 respectively, indicating the angle's component proportions as 3:4:5.**Input Fields:**- **Your Answer (Speed of B after collision):** A text box is provided for inputting the numerical value of the speed with appropriate units. The answer should be given to three decimal places.- **Units Field:** A separate field to indicate the units of the calculated speed. **Transcription for Educational Website:****Question 14:**In the image below, disk \( A \) and disk \( B \) are approaching each other, and they have masses of \( m_A = 1.7 \, \text{kg} \) and \( m_B = 1.5 \, \text{kg} \), respectively.
