Homework Help: Can anyone help me solve this problem?

  1. Jan 3, 2008 #1
    A diver finds a rectangular aluminum plate having dimensions 1.0m x 2.0m x 0.03m. A hoisting cable is lowered from the ship and the diver connects it to the plate. The density of aluminum is 2.7 x 10^3 kg/m^3. Ignore the effects of viscosity.Calculate the tension in the cable if it lifts the plate upward at a slow, constant velocity.

    Work out the volume of the plate and it's mass.
    Then work out the mass of an equal volume of water.

    How much less will the plate weigh in water?
