Alight, inextensible cord passes over a light,
frictionless pulley with a radius of 12 cm. it
has a(n) 14 kg mass on the left and a(n)
2.5 kg mass on the right, both hanging freely.
initially their center of masses are a vertical
distance 3.1 m apart.
the acceleration of gravity is 9.8 m/s. at what rate are the two masses accelerating when they pass each other
