Question

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?

A)It changes from 296 J to 432 J.
B)It changes from 379 J to 243 J.
C)It changes from 432 J to 296 J.
D)It changes from 243 J to 379 J.

Answer 1

as initially kinetic energy was 296 so potential energy was 675 - 296 = 379.
finally kinetic energy became 432 so potential energy became 675 - 432 = 243
because total energy during the process is considered to be constant
