A 1200 kg two-stage rocket is traveling at aspeed of 6.90*10^3 m/s away from the Earth when a predesigned explosion separates the rocket into two sections of equal mass that then move with a speed of 3.20*10^3 m/s relative to each otheralong the original line of motion.
A) What is the speed and direction of each section(relaive to Earth) after the explosion?
B) How much energy was supplied by the explosion? (change in kinetic energy as a result of explosion).
