2. œ A horizontal force of 100 N is required to push a piece
of furniture across a floor at a constant velocity.
(a) What is the net force acting on the furniture?
(b) How much is the friction force that acts on the
sliding furniture?
(c) How much friction acts on the furniture when it is at
rest on a horizontal surface

  • physics -

    F = ma
    a) if a = 0, the net force = 0

    b) That means that 100 + friction force = 0

    c) 0 + friction force = 0
