[ thanks for the corrections and link to ISA ] how does b depend on speed For air resistance proportional to v^2 , The Eqn is $$F_R=\frac{dA}{2}v^2$$ F_R=Resistive force d=Fluid density A=surface area So $$b=\frac{dA}{2}$$ Also what do you mean by add extra “dimensions”

I have a question : If we consider the change in g due to distance from the Earth core; then y=distance from earth’s core t=time G=gravitation constant M=Earth’s mass k=GM $$y^2(t)=\frac{k}{y(t)^2}$$ If we consider air resistive force as proportional to speed squared, then: m=falling object...

this is problem #57 from chapter 4 of "Physics for engineers and scientists vol1" ,it was solved in the book by a method the author calls "successive approximation, he first calculated the flight time of the projectile and then "corrected" for the ship's displacement. i know this is a perfectly...
