Question #115single-choiceverified

Imagine you’re running AutoX in FSA 2016. You need to limit your speed because of the following corner. What is the fastest can go at the crest/edge and still land before the beginning of the braking zone? + h = 0.25m + s = 5m + g = 9.81m/s² + Consider the car a point mass, Ignore aerodynamic effects.

Not-to-scale side-view course diagram. A small formula-style car sits on an elevated horizontal track at left, with a red point on the car and a right-pointing red velocity arrow labelled v. The track ends at a crest/edge next to an orange cone, descends via a straight downward slope, then continues horizontally with further cones. A vertical double-headed dimension h shows the height difference between the upper and lower track levels. A horizontal dimension s extends from the edge/crest to a red "BRAKE" sign farther along the lower track.
