# Physics help please :) A light, inextensible cord passes over a light, frictionless pulley with a radius of 13 cm...?

A light, inextensible cord passes over a light, frictionless pulley with a radius of 13 cm. It has a(n) 20 kg mass on the left and a(n) 4.9 kg mass on the right, both hanging freely. Initially, their center of masses are a vertical distance 1.3 m apart. The acceleration of gravity is 9.8 m/s2.

a) At what rate are the two masses accelerating when they pass each other? Answer in units of m/s2.

b) What is the tension in the cord when they pass each other? Answer in units of N.
