\fQuestion 7 The figure shows a skateboarder that is released from rest a point A. The skateboarder then moves down the track and moves past point B. There is a frictional interaction between the skateboarder and the track. Ignore heat interactions with the surroundings. . Draw an energy G/R diagram. How should we modify our energy G/R diagrams when friction is involved? A Write a conservation of energy statement. B
