So just to clarify, for any object that is rolling, it's total angular momentum is its rotational component and it's linear component times the radius?
1. Homework Statement
A spherical billiard ball of uniform density has mass m and radius R and moment of inertia about the center of mass ( ) 2 cm I = 2/ 5 mR^2 . The ball, initially at rest on a table, is given a sharp horizontal impulse by a cue stick that is held an unknown distance h above...
