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 2.20s for the boat to travel from its highest point to its lowest, a total distance of 0.690m . The fisherman sees that the wave crests are spaced a horizontal distance of 5.80mapart.

A)How fast are the waves traveling? Express the speed v in meters per second using three significant figures.

b)What is the amplitude A of each wave? Express your answer in meters using three significant figures.

Explanation / Answer

A) Apply, v = lamda*f

= 5.8*0.2272

= 1.318 m/s <<<<<<<-------ANswer

B) 2*A = 0.69

A = 0.69/2

= 0.345 m <<<<<<<-------ANswer
