1. The problem statement, all variables and given/known data I need to what the escape speed from the sun to mercury would be if the spaceship is 25 mil km away from the sun. 2. Relevant equations 3. The attempt at a solution Basically, all need to know is if I can do this: Gm1m2/radius of sun+ 25 mil km away from sun=1/2 mv^2. Also, as you get farther away you can decrease your speed. Correct?
