## A 67.0-kg person throws a 0.0470-kg snowball forward with a ground speed of 32.0 Science Assignment Help

67.0-kg person throws a 0.0470-kg snowball forward with a ground speed of 32.0 m/s. A second person, with a mass of 56.0 kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.00 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.
