thrower….. catcher……. Science Assignment Help
A 70.0kg person throws a 0.0400kg snowball forward with a ground speed of 33.0 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 2.20 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.
