For a car traveling with speed v around a banked curve of radius r a) Draw a force diagram for
the car and indicate a useful coordinate system for finding the centripetal force. b) Using the
labels from your free body diagram, write Newton's second law equations for the x and y
directions. From those equations determine a formula for the angle at which a road should be
banked so that no friction is required. c) What is this angle for an expressway off-ramp curve
of radius 154 ft at a design speed of 24.7 mph? (Note: 1 ft= 30.48 cm, 1 mi = 1.609 km, 1
hr= 60 min. 1 min= 60 s)
