Question 4 of 32 A bungee jumper who is about to jump has her energy stored entirely as
gravitational potential energy. After jumping, she bounces up and down. What
has happened to her initial gravitational potential energy when she reaches
equilibrium - that is, when she stops bouncing up and down?
O A. Some of her initial energy has been transferred to potential energy
in the bungee cord.
B. Friction and air resistance have converted all of her initial energy
to heat and sound.
C. She has regained all of her initial energy as gravitational potential
energy
D. The different energy types (gravitational potential, kinetic, and
spring potential) have balanced.
