ST 1:Two stones are simultaneously projected from level ground from same horizontal point with same speeds but different angles wuth horizontal.Both stones move in same vertical plane.Then the two stones may collide in mid air. ST 2:For two stones simultaneously projected from same point with same speed at different angles with horizontal,their trajectories may intersect at some point. Then state which st. is/are true/false and how? i.e proof.
