Question

Use a metric ruler to measure the displacement of the tip of the second hand every five seconds. That’s the distance above or below the center line that connects the 3 and the 9. Count the number as positive if the tip is above the line (towards the 12) and negative if below (towards the six). Enter each value in the tinted boxes in the Grapher tool and it will immediately plot them for you.

Answer 1

lets the  second hand lies in center line that connects the 3 and the 9 at '0' sec. By problem statement If the displacement of the second hand is above the 3-9 line , the displacement will be treated as poitive else negative.

Let the second hand starts rotating in clock wise direction.

After 5 sec , it moves from 3 to 4, the displacement will be '-1'

After 10 sec , it moves from 3 to 5, the displacement  will be '-2'

After 15 sec , it moves from 3 to 6, the displacement  will be  '-3'

After 20 sec , it moves from 3 to 7, the displacement  will be '-4'

After 25 sec , it moves from 3 to 8, the displacement  will be '-5'

After 30 sec , it moves from 3 to 9, the displacement  will be '0'

After 35 sec , it moves from 9 to 10, the displacement  will be '1'

After 40 sec , it moves from 9 to 11, the displacement  will be '2'

After 45 sec , it moves from 9 to 12, the displacement  will be '3'

After 50 sec , it moves from 9 to 1, the displacement  will be '4'

After 55 sec , it moves from 9 to 2, the displacement  will be '5'

After 60 sec , it moves from 9 to 3, the displacement  will be '0'

After 65 sec , it moves from 3 to 4, the displacement  will be '-1' And So On..
