A wad of sticky clay with mass m and velocity vi is fired at a solid cylinder of mass M and radius R (Figure P11.37). 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.
(a) Find the angular speed of the system just after the clay strikes and sticks to the surface of the cylinder.
(b) Is mechanical energy of the clay€“cylinder system conserved in this process? Explain your answer.
