1. The problem statement, all variables and given/known data
An object starts at rest at the top of the hill. There is no friction. What is the force factor at the bottom of the circular loop?
(see attachment)
2. Relevant equations
Conservation of Energy Equations
mgh, 1/2 mv^2, F_c = mv^2/r
3. The attempt at a solution
I really have no idea how to do this:
[tex] gh = .5v^2 [/tex]
[tex] v=\sqrt{2gh} [/tex]
[tex] F = \dfrac{mv^2}{r} = \dfrac{m2gh}{r} [/tex]
Then from here I don't know what to do since the radius is not given. (see diagram).
Help please :)
