Yeah that is kind of weird. For the kinetic energy, I think I just found the right formula: I found v from ##T=\frac{2\pi r}{v}##, then used ##K=\frac{1}{2} mv^2## to find kinetic energy and just added that to the potential energy difference, is that right? I get ##K=1.9364*10^{11}##, but the...

Whoops, that was a typo. It's supposed to be ##2.65*10^{10}##. And that's the distance from the center of the Earth.

Homework Statement This is from an exam for my current course in "Mechanics 2", from a couple of years ago, which means that the correct answers are given for checking results, but without further explanations. I'm confused about part (c) where my results do not correspond with the given...
