Examine the diagram. If you reduced the mass of each car involved in the crash, which of the following is most likely to occur?

• The crash will sound louder because there is more energy exchanged to the surroundings.

• The crash will sound quieter because there is less energy exchanged to the surroundings.

• The crash will sound the same because there is more energy exchanged to the surroundings.

• None of these
