A team of students conducts a series of experiments to investigate collisions. In the first experiment, the two carts collide with each other on a smooth surface. The carts stick together and continue to move forward. In the second experiment, the two carts collide with each other on a rough surface. The carts stick together and quickly come to rest. In both experiments, the initial speeds of the carts are identical. Is there a difference in the total energy of the two experiments? A. No, because the kinetic energy of the two-cart system after the collision is the same in both the experiments.
B. No, because the sum of the kinetic energy and thermal energy of the two-cart system after the collision is the same in both experiments.
C. Yes, because the kinetic energy of the two-cart system in the second experiment after the collision is less than that of the first experiment.
D. Yes, because the sum of the kinetic energy and thermal energy of the two cart system in the second experiment after the collision is less than that of the first experiment.
