Answer:
The potential energy of box of books relative to the floor is 588.6J.
Explanation:
Given that,
A box of books weighing 80kg is on a table 75cm height and we are required to find it's potential energy relative to the floor.
The data in symbolic form is
For any body of mass m situated at an height h from the ground,its potential energy with respect to ground is
Where,g=acceleration due to gravity.
Substituting the given values in the above relation we get
Therefore,
The potential energy of box of books relative to the floor is 588.6J.
