The 35-lb block is attached to two springs having a stiffness of k = 14 lb/ft . A periodic force F=(8cos3t)lb, where t is in seconds, is applied to the block.

Determine the maximum speed of the block after frictional forces cause the free vibrations to dampen out.

### Problem Description The 35-lb block is attached to two springs having a stiffness of \( k = 14 \, \text{lb/ft} \). A periodic force \( F = (8 \cos 3t) \, \text{lb} \), where \( t \) is in seconds, is applied to the block. **Objective:** Determine the maximum speed of the block after frictional forces cause the free vibrations to dampen out. **Instructions:** Express your answer to three significant figures and include the appropriate units. ### Diagram Description The diagram shows a block positioned between two springs. Both springs have the same stiffness \( k \). The periodic force \( F = 8 \cos 3t \) is applied horizontally to the block, suggesting a horizontal oscillatory motion. The setup indicates a damping effect due to frictional forces over time. ### Input Fields - Expression box to input the maximum speed (\( v_p \)) in value and units. ### Submission Press the "Submit" button to input your answer. ### Additional Options - "Request Answer" for assistance. - "Provide Feedback" for comments or questions related to this problem.
