Two forces, f1 and f2, act at a point. f1 has a magnitude of 8.60 n and is directed at an angle of 55.0 ∘ above the negative x axis in the second quadrant. f2 has a magnitude of 7.00 n and is directed at an angle of 53.2 ∘ below the negative x axis in the third quadrant. what is the x component fx of the resultant force?

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
