Transcribed Image Text: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 represented in the figure. The bob moves without friction, swinging
equally high on both sides. It moves from its turning point A through point
and reaches its maximum speed at point C.
(a) At what point does the bob have nonzero radial acceleration and zero tangential acceleration?
O A
O B
What is the direction of its total acceleration at this point?
O up
O down
O left
O right
(b) At what point does the bob have nonzero tangential acceleration and zero radial acceleration?

What is the direction of its total acceleration at this point?
O to the right and upward perpendicular to the cord
O to the left and upward perpendicular to the cord
