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 2.40s for the boat to travel from its highest point to its lowest, a total distance of 0.600m . The fisherman sees that the wave crests are spaced a horizontal distance of 6.50m apart.
1. How fast are the waves traveling?Express the speed v in meters per second using three significant figures. v=........m/s
2. What is the amplitude A of each wave?Express your answer in meters using three significant figures. A=..........m
