uu'm ) rromem a: A DlOCK With a mass or m = JG Kg rests on a Incuomess surIace and 1s SUDJBCI y to two forces acting on it. The rst force is directed in the negative xdirection with a magnitude of F1. The second has a magnitude of F 2 and acts on the body at an angle 0 = 23 measured from horizontal, as shown. .1 thcnpcrltuxnm E. $2 25% Part (2) Please use the interactive area below to draw the Free Body Diagram for this block, assuming it is in static equilibrium.

Assume that the surface it rests on is rigid. FN = m g F2 sin(9) X Attempts Remain Feedback: is available. I . A 25% Part ((1) The two forces change such that F1 = 9.5 N and F 2 = 21.5 N. Based on this change, the block may no longer be in static equilibrium. 1'3:_.1 LL- LI_'I_I_ AA_I__._A.:__ :. LL- A. J:.._4.A.:_' _ .4 _A_a____ A4- 4---1 ....... .1
