Question

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

Explanation / Answer

wavelength=6.5 m

time period=2.4*2=4.8 sec

amplitude=0.6 m

1. speed=frequency*wavelength=6.5/4.8=1.354 m/s

2. amplitude=0.6 m
