A cat with a mass of 4.5 kg is resting on top of a bookshelf that is 3 m tall. What is the cat's potential energy?

Iwould sure like to answer your question but i honestly just don’t know

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
