Alight, inextensible cord passes over a light, frictionless pulley with a radius of 8.9 cm. it has a 19 kg mass on the left and a 2.6 kg mass on the right, both hanging freely. initially their center of masses are a vertical distance 3.8 m apart. the acceleration due to gravity is 9.8 m/s^2. at what rate are the two masses accelerating when they pass each other? answer in units of m/s^2. what is the tension in the cord when they pass each other? answer in units of n.
