I need help with physics? - A 70.0 kg person throws a 0.0500 kg snowball forward with a ground speed of 32.0 m?

A 70.0 kg person throws a 0.0500 kg snowball forward with a ground speed of 32.0 m/s. A second person, with a mass of 58.0 kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.50 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.
