# What is the gravitational potential energy of a # 4 kg# object on a shelf # 3/4 m # high?

The gravitational potential energy of the object on the shelf can be calculated using the formula:

Gravitational Potential Energy (GPE) = mass * gravitational acceleration * height

Given:

- Mass (m) = 4 kg
- Height (h) = 3/4 m
- Gravitational acceleration (g) = 9.81 m/s^2 (standard value on Earth)

Plugging in the values:

GPE = 4 kg * 9.81 m/s^2 * (3/4) 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.

- If a spring has a constant of #4 (kg)/s^2#, how much work will it take to extend the spring by #78 cm #?
- A spring with a constant of #12# #kgs^-2# is lying on the ground with one end attached to a wall. An object with a mass of #5# #kg# and speed of #3# #ms^-1# collides with and compresses the spring until it stops moving. How much will the spring compress?
- 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 #12 m#, how much force is needed to raise the object?
- A ball with a mass of #350# #g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #16# # kgs^-2# and was compressed by #7/6# #m# when the ball was released. How high will the ball go?
- A machine that uses 200 watts of power moves an object a distance of 15 meters in 25 seconds. What is the force needed and the work done by this machine?
