Math Problem Statement
A buoy floating in the sea is bobbing in simple harmonic motion with amplitude 13 in and period 0.2 seconds. Its displacement d from sea level at time t = 0 seconds is 0 in, and initially it moves upward. (Note that upward is the positive direction.) Give the equation modeling the displacement d as a function of time t.
