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 statement(s) is(are) correct.

The time of flight of A TA=2×50×3510 s =6 sMaximum height attained by A , H = 502×sin23702×10 m =45 mTime taken by B to cover distance H  is given by  45 = 30 t -5t2 ⇒t=3 s
