Re: Conservation Laws

Well it's a totally inelastic collision, so:



1. momentum is conserved



2. no MECHANICAL energy is conserved.



mv = (M+m)vf



The energy that was kinetic goes into deformation of the bodies at the
impact site, and heating of the bodies (especially at the impact site).



I think you are confusing conservation of mechanical energy with
conservation of total energy.
