Question 14 of 20 A crate falling from a plane is part of a closed system that has 24,450 J of
mechanical energy. If the kinetic energy of the crate increases from 10,000 J
to 15,000 J, what happens to the gravitational potential energy of the system?
A. It decreases from 15,000 J to
10,000 J.
B. It increases from 10,000 J to
15,000 J.
C. It decreases from 14,450 J to
9,450 J.
D. It increases from 9,450 J to
14,450 J.
