1. The problem statement, all variables and given/known data 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? 2. Relevant equations ?? 3. 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.
