# A ball with a mass of #8# #kg# moving at #5# #ms^-1# hits a still ball with a mass of #32# #kg#. If the first ball stops moving, how fast is the second ball moving? How much kinetic energy was lost as heat in the collision?

The second ball will move at 1.25 m/s. The kinetic energy lost as heat in the collision is 150 J.

Since momentum is conserved, before the collision, the total momentum was:

After the collision, the momentum will remain the same, and solving the equation differently results in:

Kinetic energy is not conserved in an inelastic collision. In this instance, the kinetic energy prior to the collision is:

Following is the kinetic energy:

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
