A fish, peering from just below the water surface, spits a drop of water at the grasshopper and knocks it into the water. The grasshopper's initial position is 0.44 m above the water surface and 0.25 m horizontally away from the fish's mouth. The launch angle of the drop is 63∘ with respect to the water surface. How fast is the drop moving when it leaves the fish's mouth?
