**1. Homework Statement**

In a closed system, in an inelastic collision,

**momentum and total energy is conserved, but**

__.__

**total kinetic energy is not**But how is this possible? If we have a change in total kinetic energy, we have a change in velocity, and so we must have a change in momentum as:

momentum=mass*velocity

So I am really confused!

Thanks :)
