A light, inextensible cord passes over a light, frictionless pulley with a radius of 16 cm. It has a(n) 14 kg mass on the left and a(n) 3.2 kg mass on the right, both hanging freely. Initially their center of masses are a vertical distance 4.3 m apart. The acceleration of gravity is 9.8 m/s. At what rate are the two masses accelerating when they pass each other?
