A brick sliding across a smooth floor has a coefficient of static friction of s=0.23 and a coefficient of kinetic friction of k=0.15. If the brick has a mass of 0.85 kg, how much friction will the brick experience as it slides?

Respuesta :

Answer:

0.029325

Explanation:

0.23x0.15=0.0345

0.0345x0.85=0.029325

Answer:

1.25 N

Explanation:

It will experience friction from the kinetic friction component because it is moving ...there will be no component of static friction.

Ff = F n x  k

   =   (.85)(9.81)  x (.15) = 1.25 N
