A box is being pushed across a tiled floor with a force of 350 N. If the friction force between the box and the floor is 140 N, what is the magnitude of the net force on the box?

Question

 what is the magnitude of the net force on the box?

Answer 1

The forces are linear so we can add or subtract the forces appropriately.

Force of push one direction is offset by the force of friction the opposite direction so net force = 350 N - 140 N = 210 N
