Fn = 32 N. = Normal force.
Fap = 8 N. = Force applied.
Fap-Fs = M*a.
8-Fs = M*0 = 0.
Fs = 8 N. = Force of static friction.
Fs = u*Fn = 8.
u*32 = 8.
u = 0.25.
A block of wood experiences a normal force of 32 N from a rough,flat surface.there is a rope tied to the block.the rope is pulled parallel to the surface and the tension in the rope can be increased to 8 N before the block starts to slide.
