Tutorial Section 5.6* - Potential energy and choice of system (part 2) Now return to this problem from above: a book being accelerated downward by a hand. The book starts at a height h, above the ground and descends (falls) with constant acceleration of 11 m/s2 to a height h, above the ground. The questions below will guide you to fill in this table. Neglect air resistance. You may assume Q is zero. AE system Wext (on Q System system by (heat exchanged AKEsystem APE system external between system forces) and external world book only AKEbook = book and | AKEbook = 0 earth hane AKEearth = 11 . Compare the following for each system: the change in potential energy, the net work done on the system, and the change in kinetic energy. Explain whether this does or does not make sense to you. Be sure to double-check your signs. off to sewed Jud collings eyawla vmonal to nolisviseno 10 was unT - "Va nouns& Ishout mayoend verone show tony terd wise ew desw les edo are no'snob el how 12.

Review the table above, which you can now fill in completely. Complete the following explanation given your values from above: In the book-only system, the change in the system's total energy (AE system) is (circle one: zero, positive, negative) the book's increase in kinetic energy is due to (circle all that apply) a decrease in potential energy of the system an increase in the potential energy of the system positive work done by exactly one external force on the system positive work done by more than one external force on the system positive work done by the system on surrounding objects In the book-earth system, the change in the system's total energy (AEsystem) is (circle one: zero, positive, negative) the book's increase in kinetic energy is due to (circle all that apply) a decrease in potential energy of the system an increase in the potential energy of the system positive work done by exactly one external force on the system positive work done by more than one external force on the system positive work done by the system on surrounding objects
