A wooden block of mass 1.6kg rests on a rough horizontal surface if the limiting friction force between the block and the surface is 8N. Calculate the coefficient of friction. (g = 10ms-2)

the wooden block reest on rough surface let the force be Fs and the normal force be Fn then the cosfficient of the friction coefficient= Fs/Fn
but Fn = m g
m=1.6kg
g=10ms/s^2
Fs=8N
coefficient of friction= Fs/mg = 8/1.6 x 10 = 8/16 =0.5
