Answer 2

Answer:

0.0256m

Explanation:

We define  Coefficient of restitution (e), as  the ratio of the final to initial relative speed between two bodies after collision happen between them,

When ball dropped from above height(u=0) we have by motion's third law as

$v_f = \sqrt{2gh}$. Then,

$e = \frac{|0-\sqrt{2gh_2} |}{|\sqrt{2gh_1}-0 |} \\\implies e^2 = \frac{h_2}{h_1} \\\implies 0.16 \times 0.16 = h_2(bounce)/(1m)\\\implies h_2 = 0.0256m$
