Question
Abbas is an astronaut, floating in space. Their rocket is powered by throwing rocks out of a hole in the back of the spaceship. The inertial mass of Abbas and their rocket together is 312 kg. Abbas also (in addition to the rocket and the person) has two 37 kg rocks on board. They are initially at rest. Define an x-axis to point from the back of the rocket to the front. Abbas throws the first rock, and then they are moving with velocity component vx=8 m/s. Then Abbas throws the second rock out of the back and they are moving with velocity component vx=29 m/s .
(a) What is the total momentum of the system?
(b) With what velocity along x is the first rock Abbas threw moving through space?
(c) With what velocity along x is the second rock Abbas threw moving through space?
