1. The problem statement, all variables and given/known data The escape speed from a very small asteroid is only 32 m/s. If you throw a rock away from the asteroid at a speed of 44 m/s, what will be its final speed? 2. Relevant equations Ki + Ui = 1/2mv^2 + (-GMm/R) = 0 (for v<<c) 3. The attempt at a solution I am unsure of how to do this problem because I don't have the masses or the radius. Any help would be greatly appreciated!
