Homework Statement
If you had a track that was in the shape of a loop-de-loop and you send a small brass ball down the track, how would you calculate how much velocity is lost due to friction?
The radius of the loop is .15m.
Homework Equations
V = (2πr)/[tex]\sqrt{}(4(\pi^2)r)/g[/tex]
The Attempt at a Solution
I don't know what equation to use to find the loss of velocity due to friction so I'm not sure how to go about solving the problem.
