Two boxes hang from a solid disk pulley that is free to rotate as the blocks rise/fall.

The left box has a mass m1 = 4.3 kg and the right box has a mass m2 = 2.1 kg. The pulley has mass m3 = 2.5 kg and radius R = 0.15 m. 1)

1) What is the linear acceleration of the left box? (up is the positive direction) m/s2

2) What is the angular acceleration of the pulley? (let counter-clockwise be positive) rad/s2

3) What is the tension in the string between the left mass and the pulley? N

4) What is the tension in the string between the right mass and the pulley? N

5) The boxes accelerate for a time t = 1.51 s. What distance does each box move in the time 1.51 s? m

6) What is the magnitude of the velocity of the boxes after the time 1.51 s? m/s

7) What is the magnitude of the final angular speed of the pulley? rad/s
