**Title: Physics Problem: Calculating Speed on an Incline**---**Problem Statement:**The two blocks A and B have weights \( W_A = 68 \, \text{lb} \) and \( W_B = 12 \, \text{lb} \).**Objective:**Determine the speed of block A after it moves 3 feet down the incline, starting from rest. Assume the kinetic coefficient of friction (\( \mu_k \)) between the incline and block A is 0.2. Neglect the mass of the cord and pulleys.**Instructions:**Express your answer to three significant figures and include the appropriate units.**Input Box for Speed Calculation:**\( v_A = \)- Value: [Input field]- Units: [Input field]**Submit Button:**- Submit- Request Answer---**Diagram Explanation:**The figure illustrates a pulley system with two blocks. Block A is placed on an inclined plane, and block B is hanging vertically. The inclined plane is marked with a right triangle indicating a slope ratio of 3:4:5. A rope runs over a pulley at the top of the incline, connecting the two blocks.---
