Abody is traveling at 5.0 m/s along the positive direction of an x axis; no net force acts on the body. an internal explosion separates the body into two parts, each of mass 4 kg, and increases the total kinetic energy by 100 j. the forward part continues to move in the original direction of motion. (a) what is the speed of the rear part? (b) what is the speed of the forward part?
