@Pulsar, why is it not an answer?

Can you put a link to your source on the strength of glass?

@jimmytadams, case A is with glass that weights half of the glass in the test case. This is a very crucial difference. The density of the glass is reduced by half.

@Bernhard, I realize that the energy of the object when hitting the 1st glass is mgh, and that the energy after the impact will be the energy before minus the energy needed to break the glass. Between two consecutive impacts Energy will be added equal to (m_object+m_glass)g*h_betweensheets, but I don't know how to calculate the energy that is needed to break the glass.
