You are working on your homework when you notice some dust on the piece of paper you are writing on. You blow horizontally on the piece of paper to get rid of the dust, and you notice the piece of paper lifts off from the table. How fast did you have to blow to lift the piece of paper up? Assume the piece of paper has mass 4.5g and is a standard 8.5 by 11 inch page, the air is incompressible with a density of 1.2kg/m3. Report your answer in m/s. (Hint: find the pressure gradient force on the piece of paper.)
