A stationary 25kg object is located on a table near the surface of the earth. The coefficient of kinetic friction between the surface is 0.30. Determind the acceleratin of the object.

  • Physics -

    if it is stationary, it has no acceleration.

  • Physics -

    can u explain

  • Physics -

    if something is stationary, it does not move. acceleration means the change of velocity per time, and the change of velocity for a stationary object is zero.

  • Physics -

    but my teeacher said since Ffr is less then the horizontal force it has accelerations

  • Physics -

    oh and the Ffr is 73.5N and the horizontal force is 300N
