Two transverse pulses are traveling towards each other through a slinky. Pulse A is moving to the right, and Pulse B is moving to the left. When the pulses intersect, the slinky is completely straight. Discuss what happens to the energy of the pulses at this point.

• A. The energy is completely lost.
• B. The energy remains the same but is entirely elastic potential.
• C. The energy is partially kinetic and partially potential.
• D. The energy remains the same but is entirely kinetic.
