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 CDA = 9 ft2 for the runner. NOTE: ρAIR = 2.38x10-3 slugs/ft3, 1 horse power = 550 lb∙ft/sec.
A vehicle manufacturer is considering an engine for a new sedan (CD = 0.41, Af = 1.95 m2). The car is being designed to achieve a top speed of 75 kph on a paved surface at sea level (p = 1.225 kg/m³). The car currently weighs 1100 kg, but the designers initially selected an underpowered engine because they did not account for aerodynamic and rolling resistances. What they did not know is that the test is done on a downhill with a grade of %3D 3%. If 1.2 kg of additional vehicle weight is added for each unit of horsepower needed to overcome the neglected resistance, what will be the additional horsepower of the car if it is to achieve the 75 kph top speed? 9.962 O 8.175 4.446 None of these O 7.354 6.742 8.511
