Unformatted text preview: traveling with the correct velocity. What is the required velocity for this orbit? (The gravitational force must equal the centripetal force) c) In order to slow down, the rocket ejects a propellant with a velocity of 20,000 m/s relative to itself. The rocket engine can burn propellant at a rate of 1000 kg/s. For how long must the captain fire the rocket motors to slow his ship down enough to enter the parking orbit?...
