Running on a treadmill is slightly easier than running outside because there is no drag force to work against. Suppose a 60kg runner completes a 5km race in 23 minutes. A) Determine the drag force on the runner during the race. Suppose that the cross section area of the runner is 0.72m^2 and the density of air is 1.2mg/m^3 B) What is this force as a fraction of the runner's weight?
