Question

A car rounds a banked curve where the radius of curvature of the road is ?, the banking
angle is ?, and the coefficient of static friction is ??. Suppose that the car is traveling just fast
enough to avoid slipping down the incline, and that the center of the track is to the left of the car.
Which of the following statements must be true?

E
L.
a.
The magnitude of the normal force is mg cos 0.
b. The net force points in the -x direction.
C. The magnitude of the centripetal force is equal to FÃ sin 0 – ƒ cos 0.
d. If the radius of curvature of the track increases, then the minimum speed required to avoid
slipping down the incline must decrease.

Expert Solution

Step 1

The normal force ia the force acting perpendicular ly to the surface that os road here and the weight is acting vertically downward .

As there is fraction force component too in the vertical upward direction so mg= Ncos $θ$ -fsin $θ$
