If the object has 2,750j, what is the height of the shelf the object is resting on?

Missing information:

The mass of the object is 15 kg.

18.7 m

Explanation:

The gravitational potential energy of an object is given by

where

m is the mass of the object

g is the acceleration of gravity

h is the heigth of the object, relative to the ground

In this problem, we know:

U = 2750 J is the potential energy of the object

m = 15 kg is the mass of the object

Solving for h, we find the height of the shelf:

i think the answer is b
