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.

- An object with a mass of #3 kg# is hanging from an axle with a radius of #3 cm#. If the wheel attached to the axle has a radius of #44 cm#, how much work would it take to turn the wheel a length equal to the circumference of the axle?
- What is the gravitational potential energy of a # 9 kg# object on a shelf # 5/6 m # high?
- A ball with a mass of #450 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #36 (kg)/s^2# and was compressed by #9/8 m# when the ball was released. How high will the ball go?
- If a spring has a constant of #4 (kg)/s^2#, how much work will it take to extend the spring by #41 cm #?
- A ball with a mass of #160 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #45 (kg)/s^2# and was compressed by #1/4 m# when the ball was released. How high will the ball go?
