Abuoy floating in the ocean is bobbing in simple harmonic motion with period 5 seconds and amplitude 4ft. its displacement d from sea level at time =t0 seconds is −4ft, 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.

Step-by-step explanation:

We are given that

Period =5 s

Amplitude=4 ft

Displacement d from sea level at time

We have to find the modelling equation displacement d as a function of time.

We know that

The general equation of sinusoidal function is given by

B=

When t=0, y=d=-4 ft, D=0

Substitute the values then we get

We know that Cos(-x)=Cos x

 ()

Substitute the values then, we get
