WebIf a car rounds the curve at a speed less than 11.2 m/s, the centripetal acceleration decreases V . Therefore, the normal force, which has decreased, and the gravitational force, which is unchanged, are sufficient to accelerate the car down the inclined roadway. There are several ways to express slope: 1. as an angle of inclination to the horizontal. (This is the angle α opposite the "rise" side of a triangle with a right angle between vertical rise and horizontal run.) 2. as a percentage, the formula for which is which is equivalent to the tangent of the angle of inclination times 100. In Europe and the U.S. percentag…
