The table shows the height in centimeters, that a weight bouncing from a spring would achieve if there were no friction, for a given number of seconds.
Time (s)Height (cm)
0 0
0.75 15
1.5 0
2.25 − 15
3 0
3.75 15
4.5 0
5.25 −15
6 0
From its resting position, how long does it take the weight to bounce one direction, then the other, and then back to its resting position?
_____s
+36915 Starts t 0 at t= 0
goes positive 15 then back to zero then -15 and back to 0 at t= 3 from t=0 to t=3 is one full period = 3 seconds
