A skate boarder with mass 66 kg is skating back and for in a giant hemispherical bowl. The motion is simple harmonic. The skater starts off from rest 20 meters high in the bowl. It is timed that it takes the skater 25 seconds to get to the other side of the bowl. Which is Horizontally 313 meters from where the skater starts on the other side. (I know that is ridiculous... just pretend) assuming no energy is lost...
