A flat (unbanked) curve on a highway has a radius of 250 m
A flat (unbanked) curve on a highway has a radius of 250 m. A car successfully rounds the curve at a speed of 35 m/s but is on the verge of skidding out.
a. Draw free body diagram of the car.
b. If the coefficient of static friction between the car's tires and the road surface were reduced by a factor of 2, with what maximum speed could the car round the curve without slipping?
c. Suppose the coefficient of friction were increased by a factor of 2, what would be the maximum speed?

Two curves on a highway have the same radii. However, one is
unbanked and the other is banked at an angle of degrees. A car can safely travel along the
unbanked curve at a maximum speed under conditions when the coefficient of
static friction between the tures and the road is . The banked curve is frictionless, and the
car can negotiate it at the same maximum speed . Find the coefficient of static friction
between the tires and the...
