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.

- Suppose a force of 100 newtons is used to push an object a distance of 5 meters in 15 seconds. Find the work done and the power for this situation
- An object with a mass of #3 kg# is hanging from an axle with a radius of #2 m#. If the wheel attached to the axle has a radius of #1 m#, how much force is needed to raise the object?
- If a #2 kg# object is constantly accelerated from #0m/s# to #16 m/s# over 6 s, how much power musy be applied at #t=1 #?
- A spring with a constant of #2 (kg)/s^2# is lying on the ground with one end attached to a wall. An object with a mass of #4 kg# and speed of #1 m/s# collides with and compresses the spring until it stops moving. How much will the spring compress?
- A wrench with a length of #15 cm# is used to unscrew a #5/2 cm# bolt. If a torque of #25 Nm# is needed to overcome the friction keeping the bolt in place, what is the minimum torque that must be applied to the wrench to unscrew the bolt?
