so then... if i go about finding the height using energy... Total E= mgh+1/2mv2 and GPE equals mgh but becuase of the radius I can assume it equals mgr GPE= total E= mgr mgr=mgh+ 1/2mv2 Cancel m so I have gr=gh+1/2v2 I know all variables now except for h and v and I want to solve for v...

Okay. So to solve it I would have to find where on the surface Fn=0, like the height from the radius/ diameter of the circle. Then using that use an equation to find the angle that it comes off at? Sorry if I do not make sense. :(
