An airplane pulls a 24 kg banner on a cable as depicted in the figure below. When the plane has a constant cruising velocity the cable makes an angle of ? = 26°.
A) What is the drag force exerted on the banner by the air?
B) The weather changes abruptly and the pilot finds herself in a 20 minute rain storm. After the storm she finds that the cable now makes an angle of ?water = 35°. Assuming the velocity and drag force are the same after the storm, what is the mass of the water absorbed by the banner's fabric during the storm?
