During a Chicago storm, winds can whip horizontally at speeds of \(100\,\text{km/h}\). If the air strikes a person at the rate of \(40\,\text{kg/s}\) per square meter and is brought to rest, estimate the force of the wind on a person. Assume the person is \(1.50\,\text{m}\) high and \(0.50\,\text{m}\) wide. Compare to the typical maximum force of friction (\(\mu \approx 1.0\)) between the person and the ground, if the person has a mass of \(70\,\text{kg}\).
