An ant is crawling along a straight wire, which we shall call the xaxis, 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 58 cm , BC is 35 cm , and AO is 5 cm
A) What is the ant’s position at point A?
B) What is the ant’s position at point B?
C) What is the ant’s position at point C?
D) What is the ant’s position at point D?
Homework Answers
(A) Position at A = OA = - AO = - 5 cm
(B) Position at B = AB - AO = 58 - 5 = 53 cm
(C) Position at C = AB - BC - AO = 58 - 35 - 5 = 18 cm
(D) Position at D = POsition At A = - 5 cm
