10. (Bonus-level question) A spring with natural length 40 cm is pulled out 19 cm and released. After 4 seconds the amplitude has decreased to 14 cm. The spring oscillates 13 times each second. Find a cosine function and a sine function that model the length L of the spring/ seconds after the spring was released. (Assume the amplitude of the spring decreases exponentially.)
