7. A spring in equilibrium has length = 40 cm (0.4 m). The force exerted by the spring when it is stretched to 45 cm = 0.45 m is 400 N. That is, if the displacement is x = 0.05 m, the force is 400 N. (a) Find Hooke's constant and an expression for the force exerted by the spring in terms of the displacement x. (b) Find the work required to stretch the spring from equilibrium position to a length of 50 cm (0.5 m. That is, find the work required to stretch the spring from x=0 to x = 0.1 m
