An ideal spring is fixed at one end. A variable force F pulls on the spring. When the magnitude of F reaches a value of 49.8 N, the spring is stretched by 18.1 cm from its equilibrium length. Calculate the additional work required by F to stretch the spring by an additional 10.9 cm from that position.
