The Known:

Mass=2000kg

Velocity=50m/s

Radius=1000m

With the given information the lab worksheet I'm working on is asking me to deduce the coefficient of friction so that I can manipulate the data and answer some questions. The problem I have is that I am not entirely sure that this could be done with just the given information. BTW, this is supposed to be a car on a track.

My attempt at the solution is:

Using Fs= mv^2/r I can get 2000*50^2/1000=5000N

so the question I have is can I use this as the following Fs(max) in this equation to figure out the coefficient of static friction?

Fs(max)=μn where n is the normal force or m*g witch in this case would be 2000*9.8=19,600kgs.

If were to attempt that is would be Fx(max)/n = μ 5000/19600=.26

Is my logic sound? Please help.
