Side 7. A 10.0 kg block is at rest on a rough horizontal surface. A force of F - 50.0N @ 35° is applied to the vie block, as shown below. The coefficients of static and kinetic friction between the block and the horizontal surface are: Hs = 0.55 and thk = 0.35. Will the block move? If not, explain why not. If so, determine its acceleration. Your answer must include a free-body diagram. (Hint: compare the horizontal component of...
