**Discussion and Hints:**

The problem asks for the magnitude of acceleration at point B. For the problem, you may want to use the path description of vectors instead of the Cartesian description. Also, recall that the direction of the velocity vector is always tangential to the path and that the acceleration along the path has two components, one tangential to the path (rate of change of the tangential velocity) and one normal to the curve (the centripetal acceleration). Here's a hint for clarification. Note that *ρ* in the equation below is the radius of curvature of the path.

Also, to calculate the rate of change of velocity, you may want to look at some of the rules of differentiation, specifically, the chain rule of differentiation.
