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.

- A ball with a mass of #9 kg# moving at #14 m/s# hits a still ball with a mass of #18 kg#. If the first ball stops moving, how fast is the second ball moving?
- A ball with a mass of #2 kg# is rolling at #7 m/s# and elastically collides with a resting ball with a mass of #4 kg#. What are the post-collision velocities of the balls?
- In terms of conservation, what is the difference between an elastic and an inelastic collision?
- An astronaut with a mass of #85 kg# is floating in space. If the astronaut throws a #5 kg# object at a speed of #2/3 m/s#, how much will his speed change by?
- An astronaut with a mass of #75 kg# is floating in space. If the astronaut throws a #5 kg# object at a speed of #8 m/s#, how much will his speed change by?
