Question

A flower vase is sitting on a shelf when a gust of wind from an open

window blows it down. If the vase has a mass of 0.6 kg and the shelf is 1.5
m off the ground, what is the gravitational potential energy of the vase
before it falls?

Answer 1

8.82 J

Step-by-step explanation:

Recall that gravitational potential energy is defined as:

U = m * g * h

Then in our case, the gravitational potential energy U would be:

U = 0.6 * 9.8 * 1.5 J = 8.82 J
