i drew the forces on the block. then i found the f1 on x and y component .. f1x= 10cos40 = 7.67N f1y= 10sin40 = 6.43N i know that the sum of all forces will give me 20n, is that right? and .. the f2 is pushing the block in side < ---- but I am not sure how find the f3 on x and y component.. if...

Homework Statement Three concurrent forces, F1, F2 and F3, act on a block that is placed on a horizontal surface. The resultant force on the block is 20.0 N at 0°. If F1 = 10.0 N at 40° and F2 = 20.0 N at 180°, calculate the magnitude and direction of the force F3. Sketch a vector diagram...
