You must drag a box of books $($ m $=100$ kg $)$across a level floor horizontally at a constant speed. The coefficient of kinetic friction is uk $=0.600.$You pull the box using a rope which makes an angle of θ$=25.0$above horizontal.

$($ A $)$ Write an equation which applies Newton's $2$ nd law in the vertical $($ y $)$direction $).$

$($ B $\mathrm{) }$Write an equation which applies Newton's $2$ nd Law in the horizontal $($ x $)$direction$.$

$($ C $)$ Solve to calculate the tension force in the rope. $$
