A 66.0 kg person throwsa 0.0400 kg snowball forwardwith a ground speed of 32.0 m/s. A second person, with a massof 59.0 kg, catches thesnowball. Both people are on skates. The first person is initiallymoving forward with a speed of2.00 m/s, and the second person is initiallyat rest. What are the velocities of the two people after the snowball is exchanged? Disregard the friction between the skatesand the ice.
