A body is traveling at 4.0 m/s alongthe positive direction of an x axis; no net force acts onthe body. An internal explosion separates the body into two parts,each of mass 3 kg, and increases the totalkinetic energy by 48 J. The forward partcontinues to move in the original direction of motion.

What are the speeds of the rear part and the forward part?
