Car A uses tires for which the coefficient of static friction is 1.1 on a particular unbanked curve. The maximum speed at which the car can negotiate this curve is 25 m/s. Car B uses tires for which the coefficient of static friction is 0.75 on the same curve. What is the maximum speed at which car B can negotiate the curve?

Car A

coefficient of static friction* g = v^2/r

r = v^2 / ( g *  coefficient of static friction) = 25^2 / (9.81*1.1) = 57.918 m

Car B

coefficient of static friction* g = v^2/r

V = sqrt( r*g*coefficient of static friction) = sqrt(57.918*9.81*0.75) = 20.64 m/s

maximum speed at which car B can negotiate the curve = 20.64 m/s
