Solve the below problem:
Q: A pulley and two loads are connected by inextensible cords as shown. Load A has a constant acceleration of 10 in/s2 and an initial velocity of 8 in/s, both directed upward. Determine
(a) The number of revolutions executed by the pulley in 3 s,
(b) The velocity and position of load B after 3 s,
(c) The acceleration of point D on the rim of the pulley at time t = 0.
