Two balls A and B of mass 2kg are launched through the air from the same height (3m) and at same speed (4 m/s). If the ball A is launched straight upwards, and the ball B is launched horizontally, what is the ratio of their final velocities when they hit the ground? Your answer should complete the statement:"Ball A's final velocity is ____ times Ball B's final velocity."
