Question

Two identical balls are set into motion simultaneously form 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 the figure.

TestHub · Accepted Answer

The observer moves at v /2 horizontally. A has relative horizontal velocity + v /2 , B has − v /2 ; both fall together vertically with the same g . So the two paths are mirror-image parabolas crossing at the start, as in option (C).
