In short-track speed skating the track has straight

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.
