Question 1117620: A hanging spring is compressed 3 inches from its rest position and released at t = 0 seconds. It returns to the same position after 0.8 seconds.
Find:
a) the amplitude of the motion
b) the period of the motion
c) the frequency of the motion
d) a function that models the displacement, y, of the end of the spring from the rest position at time, t.
e) the displacement from the rest position at t= 3 min rounded to the tenths place

-------------------------------------------------
a)amplitude is the distance between the midline of a wave and its crest or trough:
3/2 = 1.5 inches
-------------------------------------------------
b) The period T is the time it takes a wave to complete one cycle:
T = 0.8s
------------------------------------
c) A wave's frequency f is the number of cycles that are completed in a certain amount of time:
1/0.8 = f 1.25 Hz
