Homework Statement
Two paint buckets, initially at rest, are connected by a lightwieght rope which is wrapped over a pulley which has a mass 2 kg and a radius of .5 m. Only conservative forces do work.
Mass A is 4 kg and starts on the ground. Mass B is 6 kg and starts 5 m above the ground.
a- Find the speed at which the top bucket hits the ground.
b- What was the average torque on the pulley?
Homework Equations
The Attempt at a Solution
a - 4.22 m/s
b- Using torque = (tension 1 - tension 2) r, I get 9.8 N for net torque. Is this correct?
