A person of 68.0 kg throws a snowball of 0.0450 kg forward with a ground speed of 27.0 m/s. The second person having a mass of 58.0 kg catches the snowball. Both the people are on skates. The first person is primarily moving forward with a speed of 2.50 m/s, and the second person is primarily at rest. Determine the velocities of the two people after the snowball is exchanged? Avoid the friction among the skates and the ice.
