A ball rolling across a flat, horizontal table has a constant velocity of v1. After it leaves the edge of the table, the ball continues to travel with a constant horizontal velocity as it begins to fall. Just before the ball hits the ground, it has a net velocity of v2. What is the ball’s vertical speed at this moment in terms of v1 and v2?
