A body is traveling at 2.0 m/s along the positive direction of an x axis; no net force acts on the body. An internal explosion sepa-rates the body into two parts, each of 4.0 kg, and increases the total kinetic energy by 16 J. The forward part continues to move in the original direction of motion. What are the speeds of (a) the rear part and (b) the forward part?
