Perfect I understand When the projectile begins to return, the velocity becomes negative and as the resistive force is proportional to v, it will change signs and therefore oppose the motion. Of course this would not happen if the resistive force is proportional to v squared. Thanks heaps

Does anyone have a solution which takes into account that the projectile when returning to the plane has the resistive force opposing it. The solutions I have seen have the resistive force acting downward for the entire flight (which is not so). Downward positive My = Mg - 0.1Mv Any comments...
