A wad of sticky clay with mass m and velocity v is fired at a solid cylinder of mass M and radius R. The cylinder is initially at rest and is mounted on a fixed horizontal axle that runs through its center of mass. The line of motion of the projectile is perpendicular to the axle and at a distance d<R from the center. Find the ratio of the final to the initial mechanical energy for m=0.01 kg, v=10 m/s, d=0.03 m, R=0.05 m, M=0.1 kg.

And momentum is constant right? So the sum of the momentum of the sticky clay and the angular momentum together are equal before and after the collision. Or L1(clay) + L1(cylinder) = L2(clay) + L2 (cylinder).
