A body falling freely from a given ht.H, hits n inclined plane at a ht.h.As a result of this impact, the direction of the velocity of the body becomes horizontal.For what ratio of h/H the body will take max. time 2 reach the ground?

Time taken = sqrt(2(H-h)/g)+sqrt(2h/g)
Which is maximum when h=H/2
