For questions 7 and 8 qualitatively complete the energy bar graph/flow diagram and write a general energy equation in terms of E, E E E and Etransferred 7. A spring loaded dart gun (initial situation) fires a dart straight up which then sticks to the ceiling with a bang (final situation). General energy equation: System/Flow Ex Eg El Ek E E E Initial Final General energy equation: 8. You pull a heavy wagon, initially at rest, through tall grass until it reaches constant velocity. General energy equation: Energy (J) System/Flow Ex Eg Eel Initial о OL Energy (J) Ek E El Eth Final 9. You and your devious friends push a 1500 kg car along a level road, accelerating it from rest. The pushers transfer 6000. J of energy into the system, 2000. J of which ends up in the Eth account due to friction. (a) Qualitatively complete the energy bar graph and energy flow diagram. (b) How fast will the vehicle be traveling after the push? System/Flow Ex Eg Eel Ek Eg Eel Eth for Initial Final
