Estimate the power needed to overcome the aerodynamic drag of a person who runs at a rate of 100 yds (300 ft) in 10 seconds into a 29.3 ft/s head-wind. Express your answer in terms of horsepower. Assume C_{D}A = 9 ft2 for the runner. NOTE: ρ_{AIR} = 2.38x10^{-3} slugs/ft3, 1 horse power = 550 lb∙ft/sec.

Step 1

note: since you have not mentioned whic part you need to get answered ,we are solving first three subpats as per our guidelines.

Step 2

given:drag force is the function of speed of the ship (V), density (rho), viscosity of fluid,diameter of the noisemaker.

P/M =5

Step 3
