Homework Statement
I don't remember exactly what the question was because it was on a quiz today. It said something along the lines of "a ladybug is on a turntable and begins to slip at .5 m/s. Find the coefficient of friction.
Homework Equations
Fc = (mv^2)/r
a = v^2/r
Ff = uFn
I think that's all I should need really for this?? Please let me know if I should be using anything else
The Attempt at a Solution
There hardly was an attempt unfortunately. I first set up the sum of the forces in the x direction. From that I had Fc - Ff = 0. I was able to cancel out mass but still had an unknown radius. Then I reread the problem, and the context made it sound like the lady bug wasn't under constant velocity (the lady bug begins to slip at .5 m/s - (to me at least) inferring that the ladybug was getting up to that speed). Overall I'm very confused. The physics department at my school is horrible, and all I really have for resources are yahoo answers and online forums.
