A block of mass 1.3 kg is resting at the base of a frictionless ramp. A bullet of mass 50 g is traveling parallel to the ramp surface at 250 m/s. It collides with the block, enters it, and exits the other side at 100 m/s.

Metals are good thermal conductors - that is, when there is a temperature difference across their ends, they transfer energy very efficiently from the higher temperature end to the lower temperature end.
