Physics Question?

You were so impressed with the problem about Super Dave that you decide that this would make a good stunt for the Institute of Technology (IT) day. To raise money for a University scholarship fund, you want to have the new IT dean bungee jump from a crane if contributions can be found for 10 scholarships. To add some interest, the jump will be made from 44 m above a 2.5 m deep pool of Jello. A 30-m long bungee cord would be attached to the dean's ankle. First you must convince the dean that your plan is safe for a person of his mass, 70 kg. The dean knows that as the bungee cord begins to stretch, it will exert a force which has the same properties as the force exerted by a spring. Your plan has the dean stepping off a platform and being in free fall for the 30 m before the cord begins to stretch. You must determine the elastic constant of the bungee cord so that it stretches only 12 m, which will just keep the dean's head out of the Jello.

A while back I located this large hole on Google earth, but I tried to show my brother this, and now can not find it anywhere. I thought it was North of Cape and South of St. Louis around the Iron mountain area in the Northeast section of the Mark Twain natl forrest. But I do not see it. Has anyone seen this, or know anything about it?

I'm looking to buy one or more books on numerical analysis. I'm interested in good and up-to-date coverage of both theory and applications, including practical issues. I would be interested in recommendations for both graduate and undergraduate-level texts and reference books.

Autumn Trail starts in Summersville & goes north 10 mi. to Fallcreek. 5 scenic spots highlight the drive, each providing parking along the narrow road with a spectacular view of a different Trail attraction; each scenic spot is at a different milepost designating its distance from Summersville in tenths of a mile.
1 No two consecutive scenic spots are the same distance apart; the longest drive between any 2 consecutive locations including end points on the Trail is 3.6 miles, while the shortest is .4 miles.
2 Distance along the Autumn Trail from Summersville-Corduroy Creek ='s the distance going north from Old Man Mountain to the White Oak Inn.
3 Amish Covered Bridge, which isn't the last scenic spot along the route, is 1 mi. south of Fallcreek.
4 Corduroy Creek spot is twice as far from the Sugar Maple Farm stop as it is from Old Man mountain viewpoint.
5 White Oak Inn & Corduroy Creek photographic opporty's lie more than 5 mi. apart
6 First scenic spot is 1.8 mi N.of Summers

in a beams ultracentrifuge, the rotor is suspended magnetically in a vacuum. Since there is no mechanical connection to the rotor, the only friction is the air resistance due to the few air molecules in the vacuum. if the rotor is spining with an angular speed of 5.0^105 rad/s and the driving force is turned off, its spinning slows down at an angular rate of 0.40 rad/s2.

How long does the rotor spin before coming to rest?
During this time, through how many revolutions does the rotor spin?

Okay, I need some help with this problem, what are the formulas i would use to solve this?

If some days we have clones of ourselves, and they are exactly like us, with emotions, passion, feeling, senses and all that stuff... should they be allowed to be used as lab rats and do you think they would have souls? Think of it this way... what if you were created to be a clone... how would you feel to be a lab rat? Since you have the mind to think that and feel what they do to you...
