By Allen Kazadi

If a car takes a banked curve at less than the ideal speed, friction is needed to keep it from sliding toward the inside of the curve (a problem on icy mountain roads). (a) Calculate the ideal speed to take a 100.0 m radius curve banked at . (b) What is the minimum coefficient of 15.0┬░friction needed for a frightened driver to take the same curve at 20.0 km / h?

Answer:

(a) v=16.2m/s

(b) u_{k}=0.237
