A1800-kg spacecraft is in a 700x1200 km altitude earth orbit. a spacecraft has a re-startable onboard propulsion system with a thrust of 12kn and specific impulse of 275s. assuming the thrust vector remains aligned with the velocity vector and that the burn time is 75 seconds, determine: a) mass of propellant expended b) eccentricity of the new orbit c) the new apogee altitude
