A 65.0 kg person throws a 0.0410 kg snowball forward with a ground speed of 28.0 m/s. A second person, with a mass of 60.0 kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.10 m/s, and the second person is initially at rest. What are the velocities of the two people after the snowball is exchanged? Disregard the friction between the skates and the ice.
a) Thrower
b) Catcher
