To raise money for a university scholorship fund, the new IT dean has volunteered to bungee jump from a crane if contributions can be found for 10 scholarshipis. To add some interest, the jump will be made from 42 m above a pool of water. A 30 m bungee cord would be attached to the dean. 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 a the force exerted by a spring. Your plan has the dean stepping off a platform and being in free fall for 30 m before the cord begins to stretch. a) Determine the spring constant of the bungee cord so that it stretches only 12 m, which will just keep the dean out of the water. (Assume that the dean is a point like object). b) Using the result of a), find the dean's speed 7 m above the water.
