2. A ball is thrown into the air at some angle . At the verry top of the balls path , how has its horizontal velocity changed? NO change? Is it greater? Less? Explain.

3. Suppose a person is able to throw a ball upwards at an angle of 90^{o .} If the person is running as fast as they can in a straight line and throws the ball straight up, where will the ball land if the person continues running forward at constant velocity?
