A concrete highway curve of radius 70.0 m is banked at a 19.0° angle
A concrete highway curve of radius 70.0 m is banked at a 19.0° angle. What is the maximum speed with which a 1900 kg rubber-tired car can take this curve without sliding? (Take the static coefficient of friction of rubber on concrete to be 1.0.)
Homework Answers
max velocity fir banked curved
v^2 = rg ( sin x + u cos x) / ( cos x - u sin x)
v^2 = 70*9.8* ( sin 19 + cos 19)/ ( cos 19 - sin 19)
v = 37. 5 m/s

do comment in case any doubt, will reply for sure.. Goodluck
