A(n) 3800 kg rocket traveling at 2500 m/s is moving freely through space on a journey to the moon. The ground controllers ﬁnd that the rocket has drifted oﬀ course and that it must change direction by 9.2 degrees if it is to hit the moon. By radio control the rocket’s engines are ﬁred instantaneously (i.e., as a single pellet) in a direction perpendicular to that of the rocket’s motion. The gases are expelled (i.e., the pellet) at a speed of 3600 m/s (relative to the rocket). What mass of gas must be expelled to make the needed course correction? Answer in units of kg.

Thank you!
