A bellow, t bin-walled sphere of mass 12.0 kg and diameter 48.0 cm is rotating about an axle through its center. The angle (in radians) through which it turns as a function of time (in seconds) is given by/J(t) = AI2 + BI4, where A bas numerical value 1.50 and B bas numerical value 1.10.
(a) What are the units of the constants A and B?
(b) At the time 3.00 s, find (i) the angular momentum of the sphere and (ii) the net torque on the sphere.
