Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_155

5/155 The load L is being elevated in accordance with the downward velocities of ends A and B of the cable. Determine the magnitude of the acceleration of point P on the top of the sheave for the instant when \(v_A = 2 \text{ ft/sec}\), \(\dot{v}_A = 0.5 \text{ ft/sec}^2\), \(v_B = 3 \text{ ft/sec}\), and \(\dot{v}_B = -0.5 \text{ ft/sec}^2\).
