A fisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. It takes 3.10 s for the boat to travel from its highest point to its lowest, a total distance of 0.620 m . The fisherman sees that the wave crests are spaced 7.60 m apart.

A. How fast are the waves traveling? (answer in m/s)

B. What is the amplitude of each wave? (answer in m)

C. If the total vertical distance traveled by the boat were 0.500 m, but the other data remained the same, how fast are the waves traveling? (answer in m/s)

D. If the total vertical distance traveled by the boat were 0.500 m, but the other data remained the same, what is the amplitude of each wave? (answer in m)
