An applied force of 50 N is used to accelerate an object to the right across a frictional surface. The object encounters 10 N of friction. Use the diagram to determine the normal force, the net force, the mass, and the acceleration of the object. (Neglect air resistance.)
this is the image she gave us: http://faculty.xavierhs.org/wertkins/ipcf1113_files/image001.gif
The picture is what is throwing me off, i thought the normal force would be what the object was actually moving at so 50n-10n= 40n. But i don't know what a net force is. I think the force of the object downward is how much it weighs so (w=m*g) 80=m*10 m=8 kg. Also to find the acceleration i dun know to use the normal force or net force in A=f/m
