An ant is crawling along a straight wire, which we shall call the c axis, from A to B to C' to D (which overlaps A), as shown in the figure below. (Figure 1) O is the origin. Suppose you take measurements and find that AB is 38 cm , BC is 17 cm , and AO is 4 cm . Part E Find the displacement of the ant after it has moved over the interval from A to B. Express your answer in centimeters. JAL cm Submit Request Answer Part F Find the distance the ant moved over the interval from A to B.
