    Metal ball sticks to putty. Where does the energy go?

    So, if the center of mass energy is not the same as the total energy, does that mean the answers to a) and b) are incorrect as well? They are also in the answer key.

    Metal ball sticks to putty. Where does the energy go?

    If energy was lost to heat, then why is the momentum the same?

    Metal ball sticks to putty. Where does the energy go?

    A 6.0kg metal ball moving at 4.0m/s hits a 6.0 kg ball of putty at rest and sticks to it. The two go on at 2.0 m/s. a) How much energy does the metal ball lose in the collision? b) How much energy does the putty ball gain in the collision? c) What happened to the rest of the energy? For a)...
