Is the momentum conserved before or after the collision? Explain. 3. I have invented a super spring that is capable of launching a 10,000 kg mass at the escape velocity of Earth (about 11 km/s). a. What would the recoil momentum of the Earth be? b. What would the Earth's recoil speed be? (Note: Earth has a mass of about 5.98 trillion-trillion kg.) What would happen if you tried to fire bullets made from neutron star material from a regular rifle? Assume that the bullet is 10 trillion times more massive than a regular bullet.
