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.

- When a body is projected vertically up from the ground, its potential energy and kinetic energy at a point P are in the ratio 1:5. if the same body is projected up with half the previous velocity then at the same point P the ratio will be what?
- A pulley system with 75% efficiency is set up to lift a 21kg bag of nails. The bag is lifted to a height of 2.3m by a person pulling on the rope with a force of 91.5N. How much work is input to the system?
- How much power is needed to accelerate an object with a mass of #4 kg# and a velocity of #8 m/s# at a rate of #2 m/s^2#?
- An object with a mass of #8 kg# is hanging from an axle with a radius of #9 m#. If the wheel attached to the axle has a radius of #18 m#, how much force must be applied to the wheel to keep the object from falling?
- An object with a mass of #24 kg# is hanging from an axle with a radius of #5 m#. If the wheel attached to the axle has a radius of #12 m#, how much force must be applied to the wheel to keep the object from falling?
