The total energy in a system is 675 j. the kinetic energy changes from 296 j to 432 j. which statement best describes the potential energy of this system?

it changes from 296 j to 432 j.

it changes from 379 j to 243 j.

it changes from 432 j to 296 j.

it changes from 243 j to 379 j.

By definition, the Total energy is given by:

Where,

U: potential energy

K: kinetic energy

We look for the value of the potential energy for the different values of the kinetic energy.

We have then:

For K = 296:

For K = 432:

Therefore, the change in power power is from 379 J to 243 J

It changes from 379 J to 243 J.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
