Consider a pendulum that is swinging back and forth to the left and to the right. If x represents the distance to the right from the center position, then x can be modeled by the horizontal coordinate of a point moving counterclockwise around a circle. A negative value of x corresponds to the pendulum being to the left of its center position. Part A: Using the given description of x, which of the points (A, B, C, D) marked in the diagram correspond to the pendulum passing through the center position? B A Part B: Which of the four points corresponds to the pendulum being at its rightmost position? Part C: Which of the four points corresponds to the pendulum passing through its center position from left to right? Part D: Graph x as a function of time and label the points A, B, C, and D, assuming the pendulum is released at the farthest right point of its path and swings once.
