Two identical balls are set into motion simultaneously from equal heights \( h \). While the ball \( A \) is thrown horizontally with velocity \( v \), the ball \( B \) is just released to fall by itself. Choose the alternative that best represents the motion of \( A \) and \( B \) with respect to an observer who moves with velocity \( v / 2 \) with respect to the ground as shown in figure.
