Balls A and B are thrown from two points lying on the same horizontal plane separated by a distance 120 m. Which of the following is true?

Two balls will meet, if (50 cos 370) tA = 120 or tA = 3 s Vertical component of A is 50 sin 370 or 30 ms-1 so they willmeet, if thrown simultaneously.hA=hB=30×3-12×10×(3)2=45 m
