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
124 ft at a design speed of 24.9 mph?
(Note: 1 ft= 30.48 cm, 1 mi = 1.609 km, 1 hr= 60 min, 1 min= 60
s)
To continue, enter the result of c) in units of
degrees.
Round your answer to 1 decimal place.
