Work Power and Energy question

2023 · 1 Feb · Shift 2 · Q66

JEE MainPhysicsWork Power and EnergyNumerical+4 / −1
A block is fastened to a horizontal spring. The block is pulled to a distance x=10 cmx=10 \mathrm{~cm}x=10 cm from its equilibrium position (at x=0x=0x=0) on a frictionless surface from rest. The energy of the block at x=5cmx=5\mathrm{cm}x=5cm is 0.25 J0.25 \mathrm{~J}0.25 J. The spring constant of the spring is ‾Nm−1\underline{\hspace{2cm}}\mathrm{Nm}^{-1}​Nm−1
