Two masses of 24 kg and 12 kg are suspended by a pulley that has a radius of 6.2 cm and a mass of 5 kg. The cord has a negligible mass and causes the pulley to rotate without slipping. The pulley rotates without friction. The masses start from rest 4.1 m apart. 4.1 m 6.2 cm 5 kg ω 24 kg 12 kg Determine the speeds of the two masses as they pass each other. Treat the pulley as a uniform disk. The acceleration of gravity is 9.8 m/s 2 . Answer in units of m/s.
