Question

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 2.50s for the boat to travel from its highest point to its lowest, a total distance of 0.610m. The fisherman sees that the wave crests are spaced a horizontal distance of 5.60m apart. A. How fast are the wave traveling? Express the speed v in meters per second using three significant figures. B. What is the amplitude A of each wave? Express your answer in meters using three significant figures.

Explanation / Answer

Part A)

Apply d = vt

v = (2.80)/(2.5)

v = 1.12 m/s

Part B)

Amplitude - .610/2 = .305m
