Answer 1

Answer:

igv6xtsxtdc6dc5dx6d5

Answer 2

Answer:

e = 0.7

Explanation:

Here, h2 = h/2

h1 = h

$e = \sqrt{ \frac{h2}{h1} }$

$e = \sqrt{ \frac{ \frac{h}{2} }{h} } \\ \: \: \: \: = \sqrt{ \frac{1}{2} }$

--------------

• Here, e = coefficient of restituition.
• Here, e = coefficient of restituition.On further simplifying ( by substituting the value of root 2, you get 0.7 as the answer.

------------

Hope it helps.....!
