you push with a 40-N horizontal force on a 2-kg box of coffee resting on a horizontal surface. The force of friction on the box is 12 N. Show that the acceleration is 4 m/s^2

  • Physics - ,

    Net force after friction
    = 40N - 12N=28N
    mass = 2kg
    Use F=ma and solve for a (acceleration).

    Note: not sure if the question is correct, either the mass=7kg or acceleration = 14 m/s².
