Václav Šmilauer posted a new comment:
Hi Eshan, if you study dynamics, you should not use the nonviscous
damping (which is the one to be used with the linear contact model)  as
that one is a purely numerical device to dissipate energy in simulations
to achieve quasi-static state: the quasi-static state is "physical" but
the dynamics involved not. You should use perhaps some of the contact
mechanics models (such as the Hertz-Mindlin, JKR, ...) which can define
coefficient of restitution. You could check
http://woodem.eu/doc/theory/contact/hertzian.html and
http://woodem.eu/doc/theory/contact/adhesive.html out for some theory
behind that. HTH, Václav
