To write an equation modeling the motion of bobber, where the high point corresponds to the time
Answer to Problem 190RE
The equation of motion of fishing bobber is
Explanation of Solution
Given information:
Fishing bobber is oscillating in simple harmonic motion caused by waves .Bobber moves a total of
Calculation:
Simple harmonic motion of a body is given by
Total distance that bobber moves from its high point to its low point :
Total time bobber takes to returns to its high point is
The equation contain cosine term since the high point of fishing bobber is at
Therefore, equation of motion of fishing bobber is given by
