Rock Powered Rocket#

Ximena is an astronaut, floating in space. Their rocket is powered by throwing rocks out of a hole in the back of the spaceship. The inertia of Ximena and their rocket together is 374 kg. Ximena also (in addition to the rocket and the person) has two 40 kg rocks on board. They are initially at rest. Ximena throws the first rock, and then they are moving with velocity m/s. Then Ximena throws the second rock out of the back and they are moving with velocity m/s .
