... If we know the normal force N from the floor acting on the box, the needed minimum horizontal force is given by F = \mu_s N. To obtain N, let us set us the equation of motion: Ma= N - Mg, where M = 1 kg, a = 3 m/s^2, so N = 12.8 N. We need \mu_s, which must be computed from the data given for a stat ...
