For 15 seconds, Anna records a weight bobbing up and down on the end of a spring. When she began recording, the weight was in motion and it was at its lowest point. From its resting position, it takes 8 seconds for the weight to bounce up to its highest position and return to it resting position. The difference between its lowest and highest points is 20 cm.
If you were to graph the position of the weight as a function of time, where the x-axis would measure in seconds and the y-axis would measure in cm, what is the coordinate point for the first point you would graph on the midline.
Spell check Then what would be the second point (labeled as a coordinate point) that would be the maximum or minimum value closest to the first point you labeled above.
