A sled is traveling down along a curve which can be approximated by the parabola y=1/4 x^2. When point B on the runner is coincident with point A on the curve (xA=2m, yA=1 m), the speed if B is measured as vB=8 m/s and the increase in speed is dvB/dt=4 m/s2. Determine the magnitude of the acceleration of point B at this instant.
