1. The problem statement, all variables and given/known data Solve the differential equation, dt/dv= 1/g (1/1-a^2*v^2) where a = (k/mg)^1/2 to yield v= 1/a(1-e^-2agt/1+e^-2agt). 2. Relevant equations F=ma Newton's 2nd Law Integration Laws 3. The attempt at a solution See image. I think I'm getting messed up on the integration laws.
