1. The problem statement, all variables and given/known data A puck of mass m is kicked up an incline (angle θ) with initial speed vo. Friction is not present, but air resistance has a magnitude of f(v) = cv2. Solve Newtons second law for the pucks velocity as a function of t on the upward journey. How long does the journey last? 2. Relevant equations 3. The attempt at a solution mr'' = -mgsinθ - fquad mv' = -mgsinθ - cv2 v(hat) dv/dt = -gsinθ -(c/m)v2 v(hat) dt = -dv/ (gsin θ -(c/m)v2 v(hat) ) I'm not quite sure how to solve this; perhaps I could rewrite to get a known integral of 1/(1 +x^2) dx, but I don't see how.
