A person of 67.0 kg throws a 0.0460 kg snow-ball forward with a ground speed of 29.0 m/s. The second person, having a mass of 58.0 kg, catches the snow-ball. Both people are on the skates. The first person is at first moving forward with the speed of 2.20 m/s, and the second person is at first at rest. Determine the velocities of the two people after the snow-ball is exchanged? Disrespect of the friction between the skates and ice.
