... (a) The work required to stretch a spring depends on the square of the amount of stretch. Therefore, to stretch a spring by the amount x requires only 1/4 the work required to stretch it by the amount 2x. In this case, the work required is W0/4. (b) To stretch this spring by 3 cm from equilibrium re ...
