1. The problem statement, all variables and given/known data A rocket through interstellar dust, no gravity. Solve for v with respect to mass. k is a constant. Drag = -bv 2. Relevant equations 3. The attempt at a solution To start: It should become a separable differential equation, but I am having a lot of trouble solving it for v(m). A hint that was given, is in the final equation you should have has m/m0 to a power.
