Problem 2? - 25: A skater, initially at rest, pushes away from the side of a skating rink as shown in the sequence of figures below. While she touches the wall she exerts a constant force on it and as a result, the wall it exerts a constant force Fill on her to the right. While she is in oontact with the wall her center of mass moves a distance (1'. During this process, the skater's internal energy change is ELEM INITIAL Problem 2?: [? points] Which of the following equations represents the energy principle ofthe point particle system as applied to the skater from the initial to the final positions shown above?
