P3-2

The ride path can be modeled as the curve (faitly shown in yellow) given by the equation shown when x=6m. If, at that instant, the scalar velocity and acceleration relative to the track is s'=1delta.deltadeltadelta m/s and s''=-0.2m/s^2, determine the absolute acceleration the the riders at that instant. Hint: this is a pure kinematics problem, gravity is irrelvant, treat the riders as particles traveling down the path.
