An engineer must design a curved exit ramp for a highway in such a way that a car, exiting at the posted speed limit of 40 mi/hr, does not depend on friction to round the curve without skidding. The radius of the curve is 161 m. At what angle with respect to the horizontal must the curve be banked?
If you are in a car that rounds a curve, and you are not wearing a seat belt, and you slide across your seat and slam against a car door, what kind of force is responsible for your slide—centripetal, centrifugal, or no force? Why is the correct answer “no force”?
A puck is sliding around a circular track that is banked at an angle ϕ with respect to the horizontal such that no friction between the puck and the track is required to keep the puck from slipping up or down the track.
