Compute all parts of given question:
Question: Running on a treadmill is slightly easier than running outside because there is no drag force to work against. Suppose a 60 kg runner completes a 5.0 km race in 23 minutes.
Part I: Determine the drag force on the runner during the race. Suppose that the cross section area of the runner is 0.72 m2 and the density of air is 1.2 kg/m3.
D =
Part II: What is this force as a fraction of the runner's weight?
D/w =
I want help to find the drag force on the runner during the race and express your answer to two significant figures and include the appropriate units.
