Three forces are exerted on an object placed on a tilted floor.Forces are vectors.The three forces are directed as shown in the figure.If the forces have magnitudes = 1.0 N, and = 7.0 N,where N is the standard unit of force,what is the component of the net force _net = ₁+ ₂+ ₃ parallel to the floor? A) 2.5 N B) 5.1 N C) 6.0 N D) 7.8 N

To find the component of the net force parallel to the floor, we need to add up the x-components of the three forces. Looking at the diagram, we can see that F1 has no x-component, F2 has an x-component of 11ea83ea_6921_3004_aeff_cf73c71a6774_TB6394_11 cos(30°), and F3 has an x-component of -11ea83ea_6921_5715_aeff_5375ddae493f_TB6394_11 cos(60°). _net = 11ea83ea_6921_3004_aeff_cf73c71a6774_TB6394_11 cos(30°) - 11ea83ea_6921_5715_aeff_5375ddae493f_TB6394_11 cos(60°) _net = 2.5 N (rounded to one decimal place) Therefore, the answer is A) 2.5 N.
