Asked by Beheshta Ismat

The table below gives the height h=f(t) in feet of a weight on a spring where t is time in seconds.
t (sec) 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30
h (feet) 4.8 7 8 8.3 8 7 4.8 2.6 1.6 1.3 1.6 2.6 4.8 7 8 8.3

(a) What is the period of f(t)?
1.6s
(include units)
(b) What is the the midline of f(t)?
(include units)

(c) What is the the amplitude of f(t)?
(include units)

h(0) = 4.8
h increases, goes back to 4.8 when t=12, then goes down and back to 4.8 at t=24
So what must the period be?
Hint -- it ain't 1.6s! where ever did you get that?

midline is at (max+min)/2
amplitude is (max-min)/2
