2.4 After you click the link, select "Friction". Set the slider for "Friction" to maximum or "Lots", and check the "Grid" box to show the heights in meters. Drag the skater to the highest point (red dot at
6m line) and let him go. Find the height he can reach each time he passes the bottom and list them in a
table. Your first column can be "How many times he passes the bottom", and it is from 0 to 5 or 6.
