A rotating uniform-density disk of radius 0.8 m is mounted in thevertical plane. The axle is held up by supports that are not shown,and the disk is free to rotate on the nearly frictionless axle. Thedisk has mass 4.4 kg. A lump of clay with mass 0.3 kg falls andsticks to the outer edge of the wheel at location A, < -0.56,0.571, 0 > m. Just before the impact the clay has a speed 8 m/s,and the disk is rotating clockwise with angular speed 0.48radians/s.
The picture of the wheel can be find at this website:

a). Just before the impact, what is the angular momentum of thecombined system of wheel plus clay about the center C? (As usual, xis to the right, y is up, and z is out of the screen, towardyou.)
