The 2.0 kg mass travels twice as far as the 4.0 kg mass before stopping. b. The 2.0 kg mass travels farther but necessarily twice as far. c. The 4.0 kg mass travels twice as far as the 2.0 kg mass before stopping. d. The 4.0 kg mass loses more kinetic energy than the 2.0 kg mass. e. Both masses travel the same distance before stopping.
