A 2kg box sits at rest on a level floor. Two children push on the box at the same time. Eli pushes horizontally to the right on the box with a force of 4N. Jamie pushes straight downward on the box with a force of 3N. The box does not move (there is friction between the box and the floor). What is the magnitude of the upward force of the floor on the box?



If needed, g=10ms2
