A gun shoots out a bullet of mass 0.6 oz. The gun mass (less the bullet) is 14 oz. It recoils with a speed of 35 mph. Find the bullet speed in mph. Star Wars travel 2 "dump their garbage before they go to light-speed" (Han) A Star Wars spaceship with fuel is initially at rest at point CG. Fuel is ejected at the back to propel the spaceship to the forward direction. After a long time, the total fuel ejected out has a center of gravity moving backward at 20 m/s. The mass of the total ejected fuel is 15 times that of the remaining spaceship. Find the forward speed of the remaining spaceship relative to CG.
