A 65kg person throws a 0.045kg snowball forward with a ground speed of 30m/s. A second person with a mass of 60kg catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.5m/s and the second person is initially at rest. What are the velocities of the two people after the snowball is exchanged? Disregard friction between the skates and the ice.
