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?
L_{i} =
0.16 ✔ Correct!
33% Part (b) What is the total moment
of inertia I_{f} with respect to the hinge, of the
rod-ball-system after the collision, in terms of the variables from
the problem statement?
I_{f} = ( ( M
L^{2} )/3 ) + m ( 2 L/3
)^{2}✔
Correct!

Part (c) What is the angular speed ω_{f}
of the system immediately after the collision, in radians per
second?
