B) the acceleration due to gravity.

C) the coefficient of static friction between the road and the tires.

D) the coefficient of kinetic friction between the road and the tires.

E) the ratio of the static frictional force between the road and the tires and the normal force exerted on the car.

A car is safely negotiating an unbanked circular turn at a speed of 19 m/s. The road is dry, and the maximum static frictional force acts on the tires. Suddenly a long wet patch in the road decreases the maximum static frictional force to one-fourth of its dry-road value. If the car is to continue safely around the curve, to what speed must the driver slow the car?

A 880-kg race car can drive around an unbanked turn at a maximum speed of 44 m/s without slipping. The turn has a radius of 120 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 9800 N on the car. (a) What is the coefficient of static friction between the track and the car's tires? (b) What would be the maximum speed if no downforce acted on the car?

In class, you have seen how to calculate the maximum speed for a car to go around a flat curve (with friction), and for a banked curve (without friction). Here, you will consider the general case. (For each question part below, include a free-body diagram.) a) (3 points) Explain briefly why the car can go around the banked curve safely even without friction, and why that is not the case for the flat curve. b) (5 points) Now consider a...

A roller-coaster track is being designed so that the roller-coaster car can safely make it around the circular vertical loop of radius R = 24.5 m on the frictionless track. The loop is immediately after the highest point in the track, which is a height h above the bottom of the loop. What is the minimum value of h for which the roller-coaster car will barely make it around the vertical loop?
