A 915 kg two-stage rocket is traveling at a speed of 5.50×10^3 m/s with respect to Earth when a pre-designed explosion separates the rocket into two sections of equal mass that then move at a speed of 4.00×10^3 m/s relative to each other along the original line of motion. What is the speed of each section (relative to Earth) after the explosion? AND How much energy was supplied by the explosion? [Hint: What is the change in KE as a result of the explosion?] Please help step by step. I've tried this problem so many times but cant get the correct answer

For any future students (likely SBU like myself), the line "4000m/s relative to each other along the original line of motion" translates to Va=Vb+4000m/s
