Problem$/$Task $6$

Two forces named vec$(a)$ and vec$(b)($see the picture on the right$)$ are acting on an $8kg$ box. Calculate the magnitude of the acceleration of the box. Describe the direction of the acceleration, for that in your picture draw the forces, draw the net force and show an angle that is related to the direction of the acceleration. Calculate that angle. NOTE: the grid represents forces measured in Newtons $($HINT: the magnitude of the vertical force is $8N).$
