Respuesta :

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
