Classical Mechanics:
A mass m has speed v_0 at the origin and coasts along the x axis in a medium where the drag force is F(v)=  c(v^3/2). I am suppose to use this vdv/dx rule which in the book is just the chain rule, i am suppose to write the equation of motion in separated form mvdv/F(v)=dx and then integrate both sides to give x in terms of v or vice versa. then show that it will ecentually travel a distance 2m(sqrt(v_0)/c).
I just don't understand the first part of the question. i don't understand how to do this separated form.
Thanks for any help
