To write an equation that describe the motion of the buoy, where the high point corresponds to the time
Answer to Problem 189RE
The equation of motion of the buoy is
Explanation of Solution
Given information:
A buoy oscillates in simple harmonic motion as waves go past. The buoy moves a total of
Calculation:
Simple harmonic motion of a body is given by
Total distance that buoy moves from its high point to its low point :
Total time that buoy takes to returns to its high point is
The equation contain cosine term since the high point of the buoy is at
Therefore, equation of motion of the buoy is given by
