1. The problem statement, all variables and given/known data What is the minimum coefficient of friction needed between the tires and the ground so you make the turn safely? Car= 1394.7kg You=75kg Radius of turn = 40m Velocity = 20m/s 2. Relevant equations Fnet = MAc (Ac = centripetal Acceleration) = Force of friction Force of Friction (Ff) = Mu(Fn) of Mu(mg) MAc = (MV^2)/r 3. 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?
