TR1 Consider the following system: Mass A = 2.40 kg and Mass B = 1.50 kg. The system is allowed to move freely without fricion. UPLOAD two graphs showing the system energy as a function of the POSITION of the masses as they move: Graph 1: Plot the energy of the system as a function of the change in position of the masses assuming no friction. Graph 2: Plot the energy of the system as a function of the change in position of the masses assuming friction is present. For each graph showr 3 lines: Potential energy of the system, Kinetic energy of the system, and Mechanical energy of the system. D1 Propose an explanation using the concepts of Work and Energy Transfer to explain the following fact: If the Chairlift engine fails, a brake system is required to prevent the Chairlift from reversing directions. H l" I|sllerlml I IHParaw vHBlI Pa'lh: p D2 Propose an explanation using the concepts of Work and Energy Transfer to explain the following fact A fully loaded Chairlift requires more energy to start than it does to maintain its motion.
