1) A 1000 kg rocket travels in outer space at 5000 m/s. The rocket then separates into two sections: a 250 kg section that travels at 8000 m/s, and a 750 kg section. All of this takes place in a straight line that you can consider as your x-axis. (Do not assume kinetic energy is constant throughout this process.)
A) What is the total momentum of the system before the separation?
B) What is the total kinetic energy of the system before the separation?
C) What is the final velocity of the more massive 750 kg rocket section?
D) What is change in the system’s kinetic energy in Joules?
