Student A and B push on a box at the same time. Th students are only pushing horizontally. No one pushed down or up on it. There is no friction. Student A pushes with a force of 14 N to the North. Student B pushes with a force of 63 N to the west. The box accelerates with a magnitude of 4.30 m/s^2. What is the magnitude and direction of the net force on the box?
