A $2\mathrm{.}0$ kg box slides up a vertical wall while you push on it at $45$ angle. What magnitude of force should you apply to cause the box to slide up at a constant speed? Assume that the coefficient of kinetic friction between the box and the wall is $0\mathrm{.}3.$

$2\mathrm{.}0$ kg

$45$vec$(F{)}_{\text{p}\text{u}\text{s}\text{h}}$
