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 quantity 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##
