Question

The 25-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.
Express your answer to three significant figures and include the appropriate units.
 
 
### Problem Description The 25-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. ([Figure 1](#)) ### Objective Determine the maximum speed of the block after frictional forces cause the free vibrations to dampen out. Express your answer to three significant figures and include the appropriate units. --- ### Figure Description The figure illustrates a block connected to two springs. Each spring has a stiffness labeled as \( k \). There is a periodic force \( F = 8 \cos 3t \) acting horizontally on the block. The setup suggests a classic mass-spring system encountering a periodic external force, demonstrating forced vibrations. ### Solution Input To submit your solution, use the following format for the maximum speed: \[ (v_p)_{\text{max}} = \text{Value (units)} \] Submit your answer for evaluation. [Submit](#Submit) [Provide Feedback](#ProvideFeedback)
