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.

- What is the gravitational potential energy of a # 13 kg# object on a shelf # 15/4 m # high?
- A ball with a mass of #80 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #14 (kg)/s^2# and was compressed by #1/5 m# when the ball was released. How high will the ball go?
- An object with a mass of #24 kg# is hanging from an axle with a radius of #16 m#. If the wheel attached to the axle has a radius of #48 m#, how much force must be applied to the wheel to keep the object from falling?
- If a rocket with a mass of 3500 tons vertically accelerates at a rate of # 3/5 m/s^2#, how much power will the rocket have to exert to maintain its acceleration at 5 seconds?
- A car accelerates down a hill that is #45.0^@# to the horizontal. If the car has a #350kW# engine and takes #2.4s# to reach the bottom, what is the force of friction resisting its motion?
