A truck hauls a replacement load of balls in its rectangular bed(Figure 4). The load is distributed along the bottom of the truck's bed according to p=Cx(y+D), where C = 3.00 lb/ft4 and D= 9.00 ft . If the bed's dimensions are l = 8.50 ft and m = 12.4 ft, what is the location of the distributed load's resultant force?
