# A buoy floating in the ocean is bobbing in simple harmonic motion with amplitude 7 ft and period 5 seconds. Its displacement d fromsea level at time t = 0 seconds is 0 ft, and initially it moves downward. (Note that downward is the negative direction.)Give the equation modeling the displacement d as a function of time t.

Step 1

Given,

Amplitude, a = 7 ft

Period = 5 seconds.

Since, d at t = 0 is 0 ft

Step 2

Now, at t = 0,...
