There are two horizontal forces on the 2.0 kg box in the overhead view of Fig. 5-43 but only one (of magnitude `F_(1)=30" N"`) is shown. The box moves along the x axis. For each of the following values of the acceleration `a_(x)` of the box, find the second force in unitvector notation: (a) `10" m"//"s"^(2)`, (b) `20" m"//"s"^(2)`, (c) 0, (d) `-10" m"//"s"^(2)`, and (e) `-20" m"//"s"^(2)`.
