	Two 75 lb. steel spheres are suspended on a 900 foot tether. Tether "X" is made with a 1/2" dia. steel cable [.46 pounds per linear foot] Tether "Y" is made with a 1/2" dia. HDPE (.98 s.g.) [.07 lbs. per foot] A current of 1.34 meters/ second is pushing on both Question No. 1: How far will the Steel tethered ball be moved away from "X" and How far will the HDPE tethered ball be moved away from point "Y" measured at the surface, HORIZONTALLY? QUESTION 2:What would be the distance IF the HDPE tether were to be 3/8" diameter? __________________ There is no recall from extinction.

	Perhaps if you had spent as much time with your homework as you did with Photo-shop, you would not be here with your assignment. That is the same people as in my high school year field trip. __________________ Bob

	If this were high school homework, either the teacher would not have understood the complexity of the problem, or the student was in a very interesting advanced math class. A true solution to the problem would require the use of vector calculus, fluid flow, and information on the properties of steel and UHMW tethers. __________________ Teaching is a great experience, but there is no better teacher than experience.
