considering the forces acting on th box and the weight of the box The acceleration of the box = 4.47 m/s^2
Weight of box = 20 kg
Forces acting on the box = 80 N north and 40 N south
Determining the acceleration of the box
acceleration = Fnet / weight of box
Fnet = [tex]\sqrt{80^2 + 40^2 }[/tex]
= [tex]\sqrt{8000}[/tex] = 89.44
∴acceleration of box = 89.44 / 20 = 4.47 m/s^2
