(III) A 725-kg two-stage rocket is traveling at a speed of 6.60 x103 m/saway from Earth when a predesigned explosion separates the rocket into two sections of equal mass that then move with a speed of 2.8x103 m/s relativeto each other along the original line of motion. (a) What is the speed and direction of each section (relative to Earth) after the explosion? (b) How much energy was supplied by the explosion?
