** 23. A 2-kg mortar shell in a fireworks display rises from the ground to a height at which it is moving directly upward at 10 m/s. At this instant, the shell explodes and splits into two pieces. A 0.5-kg piece heads off northward and exactly horizontally at a speed of 20 m/s. What is the velocity (magnitude and direction) of the second piece? What is the change in kinetic energy during the explosion? 11:gion
