Question
**Problem 14-15:** The two blocks \( A \) and \( B \) have weights \( W_A = 60 \) lb and \( W_B = 10 \) lb. If the coefficient of kinetic friction between the incline and block \( A \) is \(\mu_k = 0.2\), determine the speed of \( A \) after it moves 3 ft down the plane starting from rest. Neglect the mass of the cord and pulleys. **Diagram Explanation:** - The diagram shows block \( A \) on an inclined plane, connected to block \( B \) by a cord that passes over two pulleys. - The plane is inclined, and the angle of inclination is determined by the right-triangle with sides labeled 3, 4, and 5. - Block \( B \) is hanging vertically, indicating a gravitational force acting downward on it. - A pulley system is used to connect the two blocks, indicating that the motion of one block affects the other.
