WAR PEE b) When the two carts had different masses, which one had the greater increase in its kinetic energy? Again, what evidence supports your answer? $2. Draw a G/R energy diagram for a situation in which a spring is compressed between two carts with very different masses and the carts are then released. Also write a statement of conservation of energy for this case.Summarizing Questions S1. Consider the following questions about the changes in kinetic energy that occur when the two carts interacted with the same rubber band. a) When the rubber band was stretched by a greater amount (so the two carts were further apart when released), did the total kinetic energy of the carts increase by a greater or smaller amount? Explain why this was in terms of conservation of energy. 1 The word 'imperceptible' means that it is so small that it cannot be detected (at least by most normal means). PEF-9
