Modeling with Trigonometric Functions · Exercise 43
Create a function modeling the described behavior. Then, calculate the desired result using a calculator.
A spring attached to a ceiling is pulled down 11 cm from equilibrium and released. After 2 seconds, the amplitude has decreased to 6 cm. The spring oscillates 8 times each second. Find when the spring first comes between and effectively at rest.
