I can't seem to figure out what the damn question is asking :D. Can anyone explain what the question is asking? During a chicago storm, winds can whip horizontaly at speeds of 100 km/h. If the air strikes a person at the rate of 40kg/s per square meter and is brought to rest, calculate the force of the wind on a person. Assume the person's area to be 1.50m high and 0.50m wide. Compare to the typical maximum force of friction (μ = 1.0) between the person and the ground, if the person has a mass of 70kg. What comes to rest here? is it the air or the person? Also on a side note, can anyone explain whether the transfer of force during impulse instantaneous or not?
