Answer 1

Can you create a function to describe the motion of the buoy?

Answer 2

@heril I'm not sure how to create the function :/

Answer 3

Well, the general form for a periodic function is \(y=A\sin(Bt+C) +D\). A is the amplitude, B is based on the period, C is the phase shift and D is the vertical shift(the mean in this case)

Answer 4

I know that B = 2pi/3.5

Answer 5

So what is the amplitude of the wave here?

Answer 6

0.2?

Answer 7

Correct. And what is the mean position?

Answer 8

1.6.

Answer 9

So, if t=0, then y= the mean. Do you have the position function now?

Answer 10

y= 0.2sin(2pi/3.5 t) +1.6 ?

Answer 11

Correct. Do you know how to get the acceleration function from that?

Answer 12

differentiate the function two times?

Answer 13

Correct

Answer 14

Coolies. Thank you very much :)
