Suppose that you release a small ball from rest at a depth of 0.600 m below the surface in a pool of water. if the density of the ball is 0.300 that of water and if the drag force on the ball from the water is negligible, how high above the water surface will the ball shoot as it emerges from the water? neglect any transfer of energy to the splashing and waves produced by the emerging ball.
