The data table shows five trials where a wooden car was pushed. The car's kinetic energy was calculated before and after the work was done on the system.   Work Done (J) Initial Kinetic Energy (J) Final Kinetic Energy (J) Trial 1 0 0 0 Trial 2 0 100 100 Trial 3 100 700 800 Trial 4 200 700 900 Trial 5 400 200 600 Select all of the conclusions that can be drawn from this experiment. a. Doing work on a system increases the kinetic energy of the system. b. If no work is done to a system the kinetic energy of the object will remain constant. c. If no work is done to a system the object will stop moving. d. Doubling the amount of work done will always double the final kinetic energy of the system. e. The object with the most work done to it will have the largest final kinetic energy.
