A concrete highway curve of radius 80.0 m is banked at a 14.0[tex]\circ[/tex] angle.
What is the maximum speed with which a 1300 kg rubber-tired car can take this curve without sliding? (Take the static coefficient of friction of rubber on concrete to be 1.0.)
I was trying v_max = [tex]\sqrt{}\mu_srg[/tex]
but that didn't seem right because it didn't account for the bank of the curve.I then tried to determine normal force in the radial direction + the radial component of friction and using that as the net force to find acceleration. F_net = ma. Then using the acceleration to find velocity but i couldn't get the right answer. Any suggestions?
