Problem 1 A light rope is fixed to and wound around a pulley of mass Mp = 2.0 kg and radius r = 0.15m. A mass of m = 0.35 kg is hung from the free end of the rope. (A) If the system starts from rest and is able to rotate with negligible friction, how fast will the mass be moving after the pulley has rotated 3/4π radians? Model the pulley as a solid cylinder with the its axle through the center. Hint: Use a conservation of energy approach. Double hint: Using the Hand in Homework procedure is especially helpful for this problem. (B) Is there another set of physics concepts you could use to solve this problem and would this other approach require more or fewer steps?
