Consider two skaters, Jack (80 kg) and Jill (40 kg), who can move along a straight line (X-axis). Initially, the skaters are at rest and holding hands and their Xem is 0. Later, Jill pushes Jack away to the left. Assume there is no friction. When Jack reaches X=-4.0 m, his velocity is -2.0 m/s, (a) what is Jill's X coordinate? (b) what is Jill's velocity? (c). what is the horizontal velocity of the center of mass of the skaters? Consider two skaters, Jack (80 kg) and Jill (40 kg), who can move along a straight line (X-axis).
