2. Insert the screenshot showing the skater reached the highest point on the left side after you
placed her on the highest point of the right side of the track and released her. The reading on
the measuring tape and the Energy diagram should be visible on your screenshot.
5. Use your reading/measurement for speed from the screenshot, height of the skater at D and
the initial height of the skater to determine the default value for the acceleration of gravity g
used in the simulation. Show your work.

7. Consider that the skater moves from point E to point F. What type of energy does ue skater
have at each point? What type of energy transformation occurs while the skater moves
between from point E to point F?

8. Use your measurements for height and speed for highest initial point A, B and C and the value
you determined for g to check whether the total energy of the system is constant. Explain any
discrepancies. If you don't get any, comment on where errors could occur in this simulation
