Properties of Ocean Waves, Mastering Physics

A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. It takes a time of 2.40 s for the boat to travel from its highest point to its lowest, a total distance of 0.620m . The fisherman sees that the wave crests are spaced a horizontal distance of 5.70 m apart.

Part A:

How fast are the waves traveling?

Express the speed v in meters per second using three significant figures.

Part B:

What is the amplitude A of each wave?

Express your answer in meters using three significant answers

THIS IS THE WRONG ANSWER>>>

speed V = L./t = 5.7/2.4 = 2.375 m/s

----------------------------------

Amplitude = 0.620 m

Explanation / Answer

What you are doing wrong here is that

speed = lambda / t = 5.7 / 2*2.4 = 1.1875 m/s ----------->>>>>>>>>>>>answer)

A= 0.620m / 2 = 0.31 m
