During a fishing trip, two fishermen notice a large boulder falling into the ocean. A piece of driftwood, located 10 [m] from the position where the boulder entered the water, is lifted a maximum height of 5.0 [m] in the air due to the resulting wave. The fishermen are 100 [m] away from the position where the boulder entered the water. Assuming no dissipation of energy, how high will the wave lift the fishing vessel ?
