Transcribed Image Text:**Problem 4.3:**
A hydraulic cylinder \( D \) extends, moving the rigid rod \( ABC \), and causes the collar \( A \) to move with velocity and acceleration both to the left. Given:
- \( l_1 = 1.1 \, \text{ft} \)
- \( l_2 = 2.2 \, \text{ft} \)
- \( v_A = 5.8 \, \text{ft/s} \)
- \( a_A = 1.2 \, \text{ft/s}^2 \)
- The angle \( \theta = 32^\circ \)
Determine the speed of point \( C \).
**Important:** Numbers may change, as they are randomized. Provide your answer with two decimal places and include the appropriate unit.
---
**Diagram Explanation:**
The diagram shows a hydraulic cylinder \( D \) supporting a rod structure \( ABC \).
- Point \( A \) moves horizontally to the left with marked velocity \( v \) and acceleration \( a \).
- The rod extends from point \( A \) to point \( B \), and then to point \( C \).
- The lengths \( l_1 \) and \( l_2 \) represent segments \( BC \) and \( AB \) respectively.
- The angle \( \theta \) is between rod \( AB \) and the horizontal line.
- The speed of point \( C \) is to be calculated based on this setup.
