# A ball with a mass of #15 kg# moving at #15 m/s# hits a still ball with a mass of #17 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?

well as no external force is acting during this motion and collision,we can say,the linear momentum of the system will be conserved.

So,we can equate both,

The second ball will move at 13 m/s. The kinetic energy lost as heat in the collision is 825 J.

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.

- What is the main difference between an inelastic and a perfectly inelastic collision?
- A ball with a mass of #3 kg# moving at #4 m/s# hits a still ball with a mass of #9 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?
- How does impulse affect momentum?
- Which has more momentum, an object with a mass of #5kg# moving at #3m/s# or an object with a mass of #2kg# moving at #13m/s#?
