A cat had climbed at the top of the top of a tree. The tree is 20 meters high and the cat was 6kg. How much potential energy does the cat have? Please hurry and thanks!

About 1200J

(If we take gravity to be 10m/s^2)

Explanation:

U=mgh

m=6kg

g=10m/s^2

h=20m

U=(6)(10(20)=1200J

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
