5. Now place your skateboarder at the 6 meters mark and let the investigation play out. You can play it at Normal Speed. What happened and why?

Answer 1

If the skateboarder is placed at the 6 meters mark and the investigation is played out, the skateboarder would not move because the initial speed is 0 m/s². Since there is no initial velocity, there is no force to overcome the force of gravity pulling the skateboarder down. Therefore, the skateboarder would remain at rest at the 6 meters mark.
