# Kinetic Energy

An $\SI{8e3}{\kilo\gram}$ truck traveling at $20\text{ m/s}$ hits a parked car of mass $\SI{2e3}{\kilo\gram}$ from behind. If the collision is perfectly inelastic, what is the approximate total loss in kinetic energy?

Assume that the road is frictionless and ignore the deformation of the vehicles.

$4.8\text{ kg}$ is at rest on a frictionless floor. A bullet of mass $0.2\text{ kg}$ is fired at $500\text{ m/s}$ towards the block. If the bullet becomes embedded inside the block, how much kinetic energy is lost?
