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 0.650m . The fisherman sees that the wave crests are spaced a horizontal distance of 5.90m apart.
A. How fast are the waves traveling?
B. What is the amplitude A of each wave?
What is braking distance for the first train
