An ant is crawling along a straight wire, which we shall call the x axis, from A to B to C to D (which overlaps A), as shown in Figure 2.39. O is the origin. Suppose you take measurements and find that AB is 50 cm, BC is 30 cm, and AO is 5 cm. (a) What is the ant’s position at points A, B, C, and D? (b) Find the displacement of the ant and the distance it has moved over each of the following intervals: (i) from A to B, (ii) from B to C, (iii) from C to D, and (iv) from A to D.
