A 65.0 - kg person throws a 0.045 0 - kg snowball forwardwith a ground speed of 30.0 m/s. A second person, with a massof 60.0 kg, catches the snowball. Both people are on skates.The first person is initially moving forward with a speed of2.50 m/s, and the second person is initially at rest. What arethe velocities of the two people after the snowball isexchanged? Disregard friction between the skates and the ice.
