Academics

A pulley hanging off the side of a building supports a 0.57 kg bucket on a rope. The pulley releases rope as the bucket is lowered to the ground. The buckets starts from rest, and its acceleration downward is 3.4 m/s2. The pulley radius is 0.15 m. It takes 1.75 s for the bucket to reach ground.

a) What is the distance to ground?

b) What is the initial GPE of the bucket referenced relative to ground?

c) What is the final KE of the bucket?

d) What is the final KE of the pulley?
