A pendulum consists of a small object called a bob hanging from a light cord of fixed length, with the top end of the cord fixed, as shown in the figure. The bob moves from its turning point A, through point B, to the lowest point in its trajectory at C, where it has its maximum speed. Assume the pendulum moves without friction, swinging equally high on both sides. a) Calculate the radial component of the bob’s acceleration at Point A. b) Calculate the c) tangential component of the bob’s acceleration at point C? Roughly what is the direction of the bob’s acceleration at point B?
