Imagine a low-friction cart colliding with a rubber band with a large yellow sponge fastened to the top of the cart. The rubber band is set high enough above the surface so that, when the "sponge cart" strikes the rubber band, it is the elastic sponge that actually makes contact with the rubber band.

Consider the time between when the sponge first makes contact with the rubber band and when the sponge cart comes to a full stop. Which of the following choices best describes what happens to the elastic potential energies of the sponge and the rubber band?

A.	The EPE of both the sponge and the rubber band decrease.
B	The EPE of the sponge decreases, while the EPE of the rubber band increases.
C.	The EPE of the Sponge increases, while the EPE of the rubber band decreases.
D.	The EPE of both the sponge and the rubber band increase.
