Physics

A fisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. It takes 2.90 s for the boat to travel from its highest point to its lowest, a total distance of 0.640 m. The fisherman sees that the wave crests are spaced 7.60 m apart.

How fast are the waves traveling?
V= m/s

What is the amplitude of each wave?
A=.320m

If the total vertical distance traveled by the boat were 0.400 m, but the other data remained the same, how fast are the waves traveling ?
v= m/s

If the total vertical distance traveled by the boat were 0.400 m, but the other data remained the same, what is the amplitude of each wave?
A=.2m
