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.

- How much work does it take to raise a #41 kg # weight #5 m #?
- A force field is described by #<F_x,F_y,F_z> = < x , z, y > #. Is this force field conservative?
- A spring with a constant of #3 (kg)/s^2# is lying on the ground with one end attached to a wall. An object with a mass of #3 kg# and speed of #5 m/s# collides with and compresses the spring until it stops moving. How much will the spring compress?
- An object with a mass of #15 kg# is hanging from an axle with a radius of #24 m#. If the wheel attached to the axle has a radius of #15 m#, how much force must be applied to the wheel to keep the object from falling?
- A balanced lever has two weights on it, the first with mass #9 kg # and the second with mass #72 kg#. If the first weight is # 16 m# from the fulcrum, how far is the second weight from the fulcrum?
