A sheet of paper has a mass of 5 grams. The paper is dropped from a high building twice (it reaches terminal speed in both cases), once as a flat paper of area 600 cm2 and once crumpled as a ball of radius 2 cm. The first time it reaches terminal speed v1" and the second time the terminal speed is v2. What is the ratio v2/v1"assuming the density of air is 1.2kg/m?
