hi bro
this may help u
) Consider,
 upward gravity = -9.8 m/s2
Total time (to and fro)= 6 s, so, upward journey = 6/2 = 3 s
Initial velocity (u) = ?
Final velocity (v) = 0 m/s
From First equation of motion,
Final velocity = Initial velocity +gt
or, 0 = u + (-9.8 X3)
or, u = 29.4 m/s
So, The velocity at which ball is thrown in the upward direction is 29.4 m/s.
