<h3>Introduction</h3>Hello ! I am Deva from Brainly Indonesia will help you regarding energy and its transformation. In this case, it's the use of energy from the lifter to be equivalent to the change in the object's potential energy. Why potential energy? Because the box undergoes a change in height and the potential energy specializes at a certain height. Work (W) due to change in potential energy () can be realized in the equation :
With the following condition :
- W = work of subject (J)
= change of potential energy (J)
- m = mass (kg)
- g = acceleration of the gravity (m/s²)
= final height (m)
= initial height (m)
We know that :
- m = mass = 3.6 kg
- g = acceleration of the gravity = 9.8 m/s²
What was asked :
- W = work of subject = ... J
Step by step :
So, the energy change that occurs is 190.512 J.
