A body of mass 17.25kg rest on a smooth horizontal table. The coefficient of friction between the body and the table is 0.34. What is the horizontal frictional force that will make the body just slide.

  • Science -

    Wb = m*g = 17.25kg * 9.8N/kg = 169 N. = Wt of body.

    Fv = m*g = 169 N. = Force perpendicular to the table.
    Fs = u*Fv = 0.34*169 = 57.5 N. = Force of static friction.
