A car drives around a horizontal curve with a frictional coefficient of 0.58. What is the maximum safe speed for the carif the radius of the turn is 125m? r= 125m uk= 0.58 v=? ok I set up the problem as Fc=Ff-Fg m (v2/r)=ukFn-(m)(g) so the masses would cancel, but I'm stuck and nopt sure if I set it up right. If you anyone could give me a little help it would be appreciated.
