A variable force F is applied to a block, and the relationship between the force and the block’s displacement is shown in the figure. x1 = m, x2 = m, x3= 30 m, F1= N, F2= 30 N, and F3= N. The positive directions of the force and displacement are the same (toward right). Calculate the work done by the force as the block moves from displacement x1 to x2. Express your answer in joules (J).
