Two forces, of magnitudes F1F1F_1 = 80.0 NN and F2F2F_2 = 50.0 NN , act in opposite directions on a block, which sits atop a frictionless surface, as shown in the figure. (Figure 1)Initially, the center of the block is at position xixix_i = -6.00 cmcm . At some later time, the block has moved to the right, and its center is at a new position, xfxfx_f = 5.00 cmcm .
