You throw a ball off a desk with a constant velocity of 5 m/s. If the desk is 2 meters above the ground, a) How far horizontally will the ball go before it hits the ground? b) Find the velocity in vector form the moment right before it hits the ground? What angle does the velocity make with the x-axis?
