Question

A bungee cord stretches 2-4 times their unstretched length, and a jumper
 feels no more than 2.5-3.5g of acceleration. Assume the force in the 
cord has the math form ks-betas^3, where k and beta are constants and s is the amount 
of stretch in the cord past the unstretched length. Design a cord 
(design the constants k and beta ) so the cord stretches 2.5 times the 
unstretched length, and the acceleration of the jumper doesn't exceed 
3g, and the cord has zero stiffness at the bottom of a 400ft drop.s=elongationk=spring constant
