Asked by Henry

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