A salvage ship is attempting to raise an iron anchor off the ocean floor. The anchor has a mass of 560kg and the density of iron is 7800 kg/m^3. The cable used to lift the anchor can support a weight of 5000N before breaking. Use 1025kg/m^3 as the density of sea water . a)Will the cable be able to support the anchor while it is completely submerged? b)What is the percentage of the anchor will be out of the water when the cable breaks?

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?
