At the 2010 Winter Olympics in Vancouver, athletes from Canada’s Arctic demonstrated traditional Inuit and Dene games. In the past, these games involving strength and agility helped prepare Northerners to survive in a harsh environment.
In this photograph, the athlete is competing in the two-foot high kick (Akratcheak). The participant can either launch herself from a running or standing position with her legs no more than shoulder-width apart. With her legs parallel, the athlete must strike the suspended object with both feet. She must then land on both feet no more than a shoulder-width apart.
Through what angle from the vertical would you estimate this athlete has swung her legs to strike the suspended object? Would it be possible to draw a right triangle that contained this angle? Why or why not?
