A force with varying magnitude Fx is applied on an object and the displacement of the object is recorded in terms of x. The applied force is then plotted as a function of displacement and the curve shown in the figure is obtained. It is observed that between x = 0 and x = 9 m, the force is proportional to the square root of displacement: Fx = c√√x 18 Fr 12 6 0 0 2 4 Determine the work done by Fx on the object to move the object from: (a) x = 0 to x = 4 m (b) x = 0 to x = 9m (c) x = 4 to x = 9m 6 8 Here, Fx is measured in Newtons and x in meters, and the constant of proportionality between Fx and x is estimated to be c = 6.
