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 2.90s 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 6.50mapart.

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 figures.
