Suppose that Nolan throws a baseball to Ryan and that the baseball leaves Nolan's hand at the same height at whichit is caught by Ryan. If we ignore air resistance, the horizontal range r of the baseballis a function of the initial speed v of the ball when it leaves Nolan's hand and the angle o above the horizontal at which it is thrown.
