Galileo and Inertia
The measuring tape has two sets of small, orange cross hairs. See the image below.
Using your mouse pointer, drag the measuring tape downward until one set of cross hairs is located at the very bottom of the dip in the track. See the image below.
Use your mouse pointer to drag the other set of cross hairs to the place where the skater stopped when he rolled up the right-hand side of the track. Note: Your skater should have stopped at the line labeled with the number 6 on the right-hand side of the track.
See the image at the right. |
The number and unit in the green box by the measuring tape is roughly equal to the distance traveled by the skater after he got to the very bottom of the track. According to my measuring tape, the skater moved roughly 6.05 meters along the right-hand side of the track after he got to the bottom of the track. Your measurement should be about the same.
