A 90-kg ceiling light is suspended 4 m above the floor. What is its gravitational potential energy?

The answer to your question is Pe = 3531.6 J

Explanation:

Data

mass = 90 kg

height = 4 m

acceleration due to gravity = g = 9.81 m/s²

Formula

Potential energy = Pe = mgh

Process

Potential energy is the energy of an object due to its position.

1.- Substitution

Pe = (90)(9,81)(4)

2.- Simplification and result

Pe = 3531.6 J

b

explanation:

bc its just b
