Q-4 A fisherman notices that his boat is moving up and down periodically due to waves on the water. It takes a time of t = 5.8 s for the boat to travel from its lowest point to its highest, a total vertical distance of d = 0.92 m. The fisherman sees that the wave crests are spaced by a horizontal distance of L = 4.6 m apart. What is the velocity of the wave? Round your answer to the second decimal place
