Question

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 the figure below. O is the origin. Suppose you take measurements and find that AB is 48.0cm , BC is 28.0cm , and AO is 8.00cm.

point A = -8 cm

The ants position at point B = OB=AB -(-OA) = 48 - 8 = 40 cm

The ants position at point C = OB - BC = 40 -28 = 12 cm

The ants position at point D = OD = OA = -8 cm

Find the displacement of the ant it has moved over the interval from A to B. = 48

Find the distance of the ant it has moved over the interval from A to B. = 48

Find the displacement of the ant it has moved over the interval from B to C.

Find the distance of the ant it has moved over the interval from B to C.

Explanation / Answer

28 cm
