Engineers desire to model the magnitude of the elastic force of a bungee cord using the equation 7 - 0 [(x + 7) m-(x ² mm)² ] 7 m + 7) F(x) = a where x is the stretch of the cord along its length and a is a constant. If it takes 27.0 kJ of work to stretch the cord by 17.5 m, determine the value of the constant a (in N). XN 345 t
