Three forces of magnitudes F1 = 4.0 N, F2 = 6.0 N, F3 = 8.0 N, F4 = 5.0 N, and F5 = 5.0 N are applied to a block of mass m = 3.0 kg, initially at rest, at angles shown on the diagram. (Figure 1) All angles should be measured from the positive x axis. Calculate the magnitude of the resultant force acting on the block. What angle does the resultant force make with the positive x axis? What is the magnitude of the block's acceleration? What angle does the acceleration make with the positive x axis?
