A pulley and two loads are connected by inextensible cords as shown. Load A has
a constant acceleration of 300 mm/s and an initial velocity of 240 mm/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 t = 0.
