A balanced lever has two weights on it, the first with mass #8 kg # and the second with mass #3 kg#. If the first weight is # 2 m# from the fulcrum, how far is the second weight from the fulcrum?
So application in this case yields :

Using the principle of moments, the product of the mass and the distance from the fulcrum is equal on both sides. Thus, ( 8 , \text{kg} \times 2 , \text{m} = 3 , \text{kg} \times \text{distance} ). Solving for the distance of the second weight from the fulcrum, we get: ( \text{distance} = \frac{8 , \text{kg} \times 2 , \text{m}}{3 , \text{kg}} = 16/3 , \text{m} ), or approximately ( 5.33 , \text{m} ).

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 #15 kg# is moving at #9 m/s# over a surface with a kinetic friction coefficient of #2#. How much power will it take to accelerate the object at #3 m/s^2?
- What is the kinetic energy of an object with a mass of # 16 kg# that has been in freefall for # 4 s#?
- If a spring has a constant of #4 (kg)/s^2#, how much work will it take to extend the spring by #23 cm #?
- How much work would it take to push a # 6 kg # weight up a # 9 m # plane that is at an incline of # pi / 4 #?
- A spring with a constant of #4 (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 #3 m/s# collides with and compresses the spring until it stops moving. How much will the spring compress?
