A car rounds a banked curve where the radius of curvature of theroad is R, the banking angle is , and thecoefficient of static friction is µ.
(a) Determine the range of speeds the car canhave without slipping up or down the road. (Use mu forµ, theta for , and Rand g as appropriate in your equations.)
I viewed the post regarding this problem,entered the answer, and was told it was incorrect. I hadinput sqrt((((sintheta) -mucostheta)/((costheta) + (musintheta)))gR) for the minimumspeed and sqrt(Rg(((sintheta)+ mucostheta)/((costheta) - musintheta))) for the maximumspeed. Although I believe these to be correct, web assign issaying they are wrong. Any help with what I may have donewrong would be greatly appreciated. Thank you.
