A mass is attached to a string which is wrapped around a pulley which acts like a hoops of mass 5.0 kg and radius 0.30 m. When the mass is allowed to fall a 20N force of tension is measured in the string. A) calculate the rotational inertia of the pulley

B) what torque is applied to the pulley

C) what is the resulting angular acceleration of the pulley?

D) if the string does not slip on the pulley, what is the linear acceleration of the masses?

E) what mass was hung from the string?
