Answer :
In a case whereby box has a mass of 5.8kg the box is lifted from the garage floor and placed on a shelf if the box gains 145J of potential energy the shelf is 80.56m
How can the height be calculated?
Potential energy is a form of stored energy that is dependent on the relationship between different system components. When a spring is compressed or stretched, its potential energy increases. If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy.
potential energy [tex]PE=mgh[/tex]
h= height
m= mass
g= acceleration due to gravity
[tex]h = \frac{PE}{mg}[/tex]
=[tex]\frac{145}{1.8}[/tex]
= 80.56m
