Answer

Spring Constant= 89N/cm.

Work Step by Step

Work= Force$\times$Distance 25J= Force$\times$.075m (convert to meters) Force=333.33N ---Potential elastic energy=.5$\times$Spring Constant$\times$ Distance(substitute Potential energy for Force$\times$ Distance) Force X Distance=.5 Spring Constant X Distance 7.5cm(333.33N)=.5K$(7.5cm)^{2}$ (convert back to cm) 333.333N=.5K(7.5cm) K=89N/cm
