Question

A banked curve is designed for a roadway. The curve is designed so that a car traveling at 19.2 m/s can negotiate it without relying on the force of static friction. The radius of the curve is 51.2 in and the car has a mass of 2300 kg. What angle is the curve banked at (degrees)? What is the magnitude of the Normal force (N) between the road and the car when it is traveling at the designed speed? If a careless driver tries to negotiate the curve at a speed of 25 m/s. will the direction of the frictional force be inward or outward?

Explanation / Answer

a.36.3= b. 28000=m*g/cos(36.3) c. inward
