Am1= 25-kg object and a m2 = 8-kg object are suspended, joined by a cord that passes over a pulley with a radius of R = 10 cm and a mass of M = 4.2 kg as seen in %3D %3D the Figure. The cord has a negligible mass and does not slip on the pulley. The pulley rotates on its axis without friction. The objects start from rest d = 4.7 m apart. Treat the pulley as a uniform disk, and determine the speeds of the two objects as they pass %3D each other. (Your result must be in units of m/s and include 2 digit after the decimal point. Maximum of 4% of error is accepted in your answer. Take g = 9.80 m/s 2) %3D Hint: For solid cylinder of disk the moment of inertia about an axis through center of mass is IcoM =,MR %3D
