Homework Statement
A space probe with mass of 7.60 * 10^3 kg is traveling at 125 m/s. Missions control decides that a course correction of 30 degrees is needed. and instructs probe to fire rockets perpendicular to present direction of motion. If gas expelled by rockets has speed of 3.200 km/s, what mass of gas should be released?

The Attempt at a Solution
3.200 km/s-->3200 m/s
I'm totally stuck on this one. I'm not good at physics, so I need someone to walk me through this problem thoroughly.
Thanks in advance.
