A rod of mass *M* = 3.35 kg and length *L* can rotate about a hinge at its left end and is initially at rest. A putty ball of mass *m* = 65 g, moving with speed *v* = 4.37 m/s, strikes the rod at angle *θ* = 48° from the normal at a distance *D* = 2/3 *L*, where *L* = 0.85 m, from the point of rotation and sticks to the rod after the collision.

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?
