The set up in the diagram below relates to a classic inclined plane problem that is typically solved using free body diagrams and Newton's Second Law of Motion. You will work through this inclined plane problem using Conservation of Mechanical Energy instead. You may ignore friction and assume that the system is initially at rest. (a) If m 1 falls down 4.9 m, what is the change in potential energy Δ U 1 of m 1 ? Leave your answer in terms of m 1 and g . Note: A positive answer indicates an increase in potential energy and a negative answer indicates a decrease in potential energy. (Use the following as necessary: m_1 for m 1 and g.) Δ U 1 = m1g(-4.9) (b) Notice that the string connecting m 1 and m 2 does not stretch but remains taut. What is the corresponding change in potential energy Δ U 2 of m 2 ? Leave your answer in terms of m 2 , g , and θ . Note: A positive answer indicates an increase in potential energy and a negative answer indicates a decrease in potential energy. (Use the following as necessary: m_2 for
