Answer all questions for the case under which he just barely loses contact with the ground as he reaches the top of the hill as shown. Neglect drag and the size of the skateboarder. Number of forces: Force(s) towards center: Are all forces balanced? What is the centripetal net force on the skateboarder? N What is the skateboarder's centripetal acceleration? m/s What is the skateboarder's speed? m/s Would the skateboarder catch air if he reached the peak of the hill with a speed of 10m/s? 13m |||
