... 2. Find a solution for the motion of an object of mass m with initial velocity v0 , moving through a fluid that produces both linear and quadratic fiscous drag, that is, find x(t) when the only forces acting on the object are Fdrag = −c1 v − c2 v|v|. Consider separately the two cases when the initi ...
