The sphere shown in figure lies on a rough plane when a particle of mass 'm' traveling at a speed v0 collides and sticks with it. If the line of motion of the particle is at a distance h above the plane, find the angular speed of the combined system just after the collision. Assume that the mass M of the sphere is large compared to the mass of the particle so that the center of mass of the combined system is not appreciably shifted from the center of the sphere.
where does the center of mass of a two particle system lie when one particle is more massive than the other?
