Homework Statement
"In more than one way, find the loss of energy of the ball as it rolls down the ramp."
If for one method, I use WNon-conservative force = Change in Energy, would the work be by kinetic friction?
If it is, then how would I find the work done by friction (which is the NCF) if I only have the following information:

Mass of ball = 0.0083 kg
Homework Equations
Uk = Ffriction/ Normal
WNCF = Change in energy
N = mg
The Attempt at a Solution
This is where I got stuck - I tried to find Ffriction but I don't have Uk.
