Two hangers are attached by a string to a vertically mounted pulley system as shown. One disk is bigger than the other, and the disks are attached to each other such that they rotate together. The axle has negligible friction. The mass of the large disk is 1200 grams and the radius is 11 cm. The mass of the small disk is 400 grams and the radius is 4 cm. The high hanger has a mass of 200 grams and starts 80 cm above the ground. The lower mass starts on the ground and has a mass of 100 grams. The hangers are released from rest. What is the velocity of the 200 gram hanger when it hits the floor?

Question
Two hangers are attached by a string to a vertically mounted pulley system as shown. One
disk is bigger than the other, and the disks are attached to each other such that they rotate
together. The axle has negligible friction. The mass of the large disk is 1200 grams and the radius is 11 cm. The mass of the small disk is 400 grams and the radius is 4 cm. The high hanger has a mass of 200
grams and starts 80 cm above the ground. The lower mass starts on the ground and has a
mass of 100 grams. The hangers are released from rest. What is the velocity of the 200
gram hanger when it hits the floor?
