Solve the all parts of given problem:
Problem: In short-track speed skating, the track has straight sections and semicircles 16 m in diameter. Assume that a 68kg skater goes around the turn at a constant 12m/s.
Part I: What is the horizontal force on the skater?
F =
Part II: What is the ratio of this force to the skater's weight?
F/W =
I want help to find the ratio of this force to the skater's weight and express your answer to two significant figures and include the appropriate units.
