Question
Modeling with periodic functions: Cyclical exponential decay. A spring is
attached to the ceiling and pulled 17 cm down from equilibrium and released.
After 4 seconds the amplitude has decreased to 10 cm. Also, the spring oscillates
12 times each second. Assuming that the amplitude is decreasing exponentially,
below is a model for the distance, D the end of the spring is below equilibrium,
in terms of seconds, t:
D(t) = 17(0.87577)' · cos(24rt) .
[Note: Here we define t as the number of seconds elapsed. Also, locations below
the resting position have negative values for D.]
After t = 6 seconds, how far from equilibrium is the end of the spring?
your answer is a decimal, please round to no more than 3 decimal places.
