• HE'S BACK! In previous HW assignments (HW 10 and 14), we found that when we ignored the mass of the pulley, the man's speed was 11.35 ft/s when he hit the ground. Repeat the problem if the pulley is assumed to be a solid disk with a weight of 300 lb and a radius of 3 feet. Use work and energy. This 200-lb man A holds a rope that passes over pulley B and is attached to a 100-1b crate C. When he steps off the platform, he falls 6 feet to the ground as the crate rises. At what speed does he hit the ground? 90 90 B A 6 ft с
