A putty ball of mass m = 45 g, moving with speed v = 6.05 m/s, strikes the rod at angle = 41° from the normal at a distance D = 2/3 L, where L = 1.05 m, from the point of rotation and sticks to the rod after the collision. m M Otheexpertta.com 33% Part (a) What is the initial angular momentum of the ball, in kilogram meters squared per second, right before the collision relative to the pivot point of the rod?
