A block of mass M2 = 4kg hangs from a rope that is wrapped around a frictionless pulley and connected to another mass M1 = 2kg that is at rest on a frictionless table. The mass of the pulley is 2kg and its radius is 0.1m. When the blocks are released:

a) What is the acceleration of the masses?
b) What is the tension, T1, in the rope?
c) The magnitude of the net torque exerted on the pulley is?

See the attached document for a diagram.
