Question

A 2.5 kg cat is resting on top of a bookshelf that is 3 meters high. What is the cats gravitational potential energy relative to the floor if the acceleration due to gravity is 9.8 m/s ^2

Answer 1

The answer to your question is Ep = 73.6 Joules

Step-by-step explanation:

Data

mass = 2.5 kg

height = 3 m

gravity = 9,81 m/s²

Potential energy = ?

Potential energy is the energy stored in an object due to its position, the highest the object be, the highest the potential energy.

Formula

Pe = mgh

Substitution

Ep = (2.5)(9.81)(3)

Simplification and result

Ep = 73.6 Joules
