 8%) Problem 15:   A rod of mass M = 3.5 kg and length L can rotate about a hinge at its left end and is initially at rest. A putty ball of mass m = 55 g, moving with speed v = 6.68 m/s, strikes the rod at angle θ = 59° from the normal at a distance D = 2/3 L, where L = 1.25 m, from the point of rotation and sticks to the rod after the collision.
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?
 Li = 0.16     ✔ Correct!

33% Part (b) What is the total moment of inertia If with respect to the hinge, of the rod-ball-system after the collision, in terms of the variables from the problem statement?
 If = ( ( M L2 )/3 ) + m ( 2 L/3 )2     ✔ Correct!
33% Part (c) What is the angular speed ωf of the system immediately after the collision, in radians per second?
