A ball rolling across a flat horizontal table has a velocity of V1 . After it leaves the edge of tjhe table, it continous to travel with a constant horizontal velocity as it begins to fall just before the ball hits ground it has a net velocity of V2. What is the balls vertical speed at this moment.
