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.

- If a spring has a constant of #4 (kg)/s^2#, how much work will it take to extend the spring by #8 cm #?
- The force applied against a moving object travelling on a linear path is given by #F(x)= cosx + 2 #. How much work would it take to move the object over #x in [ 0, (13 pi) / 6] #?
- An object with a mass of #1 kg# is hanging from an axle with a radius of #16 m#. If the wheel attached to the axle has a radius of #84 m#, how much force must be applied to the wheel to keep the object from falling?
- The force applied against an object moving horizontally on a linear path is described by #F(x)=x^2+ 5 #. By how much does the object's kinetic energy change as the object moves from # x in [ 1, 2 ]#?
- A spring with a constant of #5 (kg)/s^2# is lying on the ground with one end attached to a wall. An object with a mass of #6 kg# and speed of #8 m/s# collides with and compresses the spring until it stops moving. How much will the spring compress?
