The SpaceX DragonLab capsule needs to change its orbit by 15 meters/second to catch up to and rendezvous with the International Space Station (ISS). The SuperDraco maneuvering thrusters on DragonLab have an Isp of 235 s, and DragonLab's initial mass is 6,000 kg. How much propellant will the maneuver require?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec
