bumper cars colliding- inelastic

man jumping in a cab- perfectly inelastic

mud sticking to car - perfectly inelastic

hat being sat on door being slammed- inelastic

ball bouncing- elastic

Explanation:

In a perfectly inelastic collision, the objects stick together after collision and move with a common velocity. Maximum kinetic energy is lost during such collision.

For an inelastic collision, kinetic energy is partly lost and the colliding objects move apart at different velocities. This is often encountered in real life situations.

For an elastic collision, both momentum and kinetic energy are conserved. The object rebounds with the same relative velocity with which it approached.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
