## Homework Statement

a ball of mass 0.1 kg, is free falling from the height (h1) of 1 m. hits the ground with a k = 0.5.

##k=\frac{v_2}{v_1}##

A)Height that the ball will reach after the hit.

B)The heat quanity released by collision

## Homework Equations

I think ##mgh## and ## \frac{mv^2} {2} ##

## The Attempt at a Solution

I found ##h_2## = 0,1 m , is this correct? .

divided the process in 2 steps :

##mgh_1= \frac {mv^2_1}{2}## and found ##v_1=\sqrt{2gh_1}##

and then did the same for the other 2 parts of the "movie"

##mgh_2= \frac {mv^2_2}{2}## and found ##h_2=\frac{v_2^2}{2g} ##

then I just replaced ##v_2## and calculated ##h_2##
