A billiard ball can stop short when hitting another billiard ball, but only if the collision is exactly head on, meaning that the trajectory of the outgoing ball is along the same line as the first. (i) Why

The 20@kg wheel has a radius of gyration about its center g of kg = 300 mm. when it is subjected to a couple moment of m = 50 n # m, it rolls without slipping. determine the angular velocity of the wheel after its mass center g has traveled through a distance of sg = 20 m, starting from rest.
