Homework Statement
What is the minimum coefficient of friction needed between the tires and the ground so you make the turn safely?[/B]
Car= 1394.7kg
You=75kg
Radius of turn = 40m
Velocity = 20m/s
Homework Equations
Fnet = MAc (Ac = centripetal Acceleration) = Force of friction
Force of Friction (Ff) = Mu(Fn) of Mu(mg)
MAc = (MV^2)/r[/B]
The Attempt at a Solution
(MV^2)/r = Mu(Mg) mass cancels out and i solve for mu ==> mu = (V^2/rg)
mu = 20^2 / (40*9.8)= 1.02
If that is correct is it possible for the friction coefficient to be more than 1?
