19. Sebuah benda dengan massa 4 kg memiliki energi potensial sebesar 1.00 ) Joule. Apabila diketahui gravitasi bumi sebesar 10m/s^2, tentukan ketinggian benda tersebut dari permukaan bumi!

0.25 m

The question is asking for the height from the surface of the earth a 4 kg object is at if it has 1.00 Joule of potential energy. The formula for potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height. We can rearrange this formula to solve for h: h = PE / (mg). Substituting the given values in, we get h = 1.00 Joule / (4 kg * 10 m/s^2).
