If an object is launched at escape velocity from the surface of the Earth, how long will it take to reach a given height h? Ignoring air resistance and other gravity, etc.
Err, I should note that I know *how* to find it, and that what I can't seem to figure out is how to put it into a formula, with 3 variables representing the 3 sets of sides.
I'm trying to figure out how to find the longest diameter of any irregular hexagon with 3 different sets of sides. Each side is the same in length as the side opposite it, and different in length to both sides beside it. Any help?
