Question

The table below gives the height h=f(t)h=f(t) in feet of a weight on a spring where t is time in seconds.
t (sec) 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
h (feet) 4.6 2.6 1.6 1.3 1.6 2.6 4.6 6.6 7.6 7.9 7.6 6.6 4.6 2.6 1.6 1.3

(a) What is the period of f(t) f(t)?
1.6ft
(include units)
(b) What is the the midline of f(t) f(t)?
4.6ft
(include units)

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

Answer 1

a)
Period is 7 seconds

b)
Midline is at 4.6 ft

c)
Amplitude is: 7.9 - 4.6
Amplitude = 3.3 ft
