SOLUTION: Please help :) The vertical motion of a rubber raft on a lake approximates simple harmonic motion due to the waves. If the amplitude of the motion is 0.250 m and the period is 3

Question 179234: Please help :)
The vertical motion of a rubber raft on a lake approximates simple harmonic motion due to the waves. If the amplitude of the motion is 0.250 m and the period is 3.00 s, find an equation for the vertical displacement y as a function of the time t. SKETCH two cycles.

-----------------------------
Form: y = asin(bx+c)
-----------------------------
a = amplitude = 0.25
period = 2(pi)/b = 3 seconds
Therefore b = (2/3)pi
-----------------------------
Equation y = 0.25sin[(2/3)pi]
------------------------------
