Twо identicаl 2.0 kg cаrts аre rоlling tоward each other on a track. Cart A is moving right at 3.0 m/s, and Cart B is moving left at 3.0 m/s. They collide head-on and stick together (Velcro bumpers). a) What is the velocity of the carts after the collision? Show your calculation. b) A student calculates the total kinetic energy of the system before the collision and after the collision. He looks at this result and says, "Wait, the energy disappeared! This violates the Law of Conservation of Energy." Do you agree with the student? Explain with reasoning using specific numerical values to support your answer.
