Dear Student,
at first when the body is dropped, u=0, remove voyaged is 16m in this manner last speed before hitting the ground is
v2=u2+ 2as
v2= 2x gx 16.
since 25% dynamic vitality is lost in impact, the vitality left in the body is 75%
in this manner 75/100 x 1/2mv2= mgh
where h is the separation to which it bounce back.
Cheers!!
