Physics

A hollow, thin-walled sphere of mass 11.0 kg and diameter 48.0cm is rotating about an axle through its center. The angle (inradians) through which it turns as a function of time (in seconds)is given byθ(t)=At2+Bt4,where A has numerical value 1.20 and Bhasnumerical value 1.60.

At the time 3.00 s , find the angular momentum of thesphere.

At the time 3.00 s , find the net torque on the sphere.
