If the track descends a distance h for every full revolution, determine the magnitude of the roller coaster’s acceleration as it moves along the track, r of radius. Hint : For part of the solution, note that the tangent to the ramp at any point is at an angle φ = tan -1 ( h /2 π r ) from the horizontal. Use this to determine the velocity components v and v z which in turn are used to determine and
