A sled is traveling down along a curve which can be approximated by the parabola y = 
x2. 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.

In this, there are 2 accelerations that is radial (ar), tangential (at).
Radial is given by ar= (v^2) /radius of curvature.
Here radius of curvature is 32^0.5.
A = [at^2 + ar^2]^0.5.
Radial is given by ar= (v^2) /radius of curvature.
Here radius of curvature is 32^0.5.
A = [at^2 + ar^2]^0.5.
