Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the door. One child pushes with a force of 16.4 N at a distance of 0.590 m from the hinges, and the second child pushes at a distance of 0.470 m. What force must the second child exert to keep the door from moving? Assume friction is negligible.

1. F1 * d1 = F2 * d2.
16.4 * 0.590 = F2 * 0.470.
F2 = ?
