Tension and water density

You are fishing off a bridge and feel a tug on the vertical line. This time, your lucky catch is an old boot. (a) Assume that the boot is not punctured, so that as you lift it out of the water at constant speed, you haul up one bootful, or 7500 cm^3, of water along with the boot. If the neoprene rubber making up the boot has volume 435 cm^3 and density 1240 kg/m3, then what is the tension on your fishing line after you pull the boot out of the water? (b) What is the tension in your fishing line before you pull the boot out of the water? Ignore any drag forces.


Any one know how to do this???
