The curves on a race track are banked to make it easier for cars to go around the curves at high speed. Draw a free-body diagram of a car on a banked curve. From the motion diagram, find the direction of the acceleration.
(a) What exerts the force in the direction of the acceleration?
(b) Can you have such a force without friction? (Explain.)
