1. The problem statement, all variables and given/known data What is the escape velocity for an object on the surface of a 1.9x10^27kg planet of radius 7.2x10^7m? 2. Relevant equations Ve = √2GM/r 3. The attempt at a solution What I did was take the values for the mass and radius directly from the question then I plugged them into the above equation and the answer I got is 5.9x10^4m/s. I was just wondering is this correct or am going wrong somewhere because it seems like there is more to this question?
