A block is pulled by a force X in a straight line along a rough horizontal surface, as shown in Fig. 3.1. total resistive force 0.80 N horizontal surface velocity X Fig. 3.1 Assume that the total resistive force opposing the motion of the block is 0.80 N at all speeds of the block. The variation with time t of the magnitude of the force X is shown in Fig. 3.2. 0 0 1 2 3 4 5 6 0.5 1.0 1.5 2.0 X / N t / s Fig. 3.2
