Homework Answers
Say the force applied is 10 Newton and the maximum frictional force offered by the surface is 15 Newton. In this case the frictional force acting would be only 10 Newton just to oppose the motion and not 15 @@Newton because it would make the body to move in opposite direction.

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...
