Physics: If a wooden block of 1.93 kg is being pushed with a force of 4.57 Newtons in the horizontal direction. The box is on a horizontal surface that has static friction coefficient of 0.43 and a kinetic friction coefficient of 0.26. What is the size of the frictional force the block is experiencing if the block is not moving?

Explanation:

Given

mass of block $m=1.93\ kg$

Force acting on the block $F=4.57\ N$

Coefficient of static Friction $\mu _s=0.43$

Coefficient of kinetic Friction $\mu _k=0.26$

If the block is not moving then static friction is opposing the force acting

Static friction $=\mu _sN$

where N=Normal reaction

N=mg

$f_s=0.43\times 1.93\times 9.8=8.133\ N$

Static Friction will auto adjust itself according to the applied force .

So $static\ friction =Applied\ friction=4.57\ N$
