a cylindrival shell of mass 3.kg and diameter 15cm starts to rotate from rest around its central axis with a constant angular acceleration. it takes 2 minutes for the cylindrical shell to make 30 revolutions.

a) Find the magnitude of the net torque exerted on the cylindrical shell when the cylindrical shell made 30 revolutions from rest?

b)Find the magnitude of the total linear acceleration when the cylindrical shell made 20 revolutions from rest.

c)Find the angular momentum when the cylindrical shell made 10 revolutions from rest
