While exploring a castle, Exena the Exterminator is spotted by a dragon that chases her down a hallway. Exena runs into a room and attempts to swing the heavy door shut before the dragon gets her. The door is initially perpendicular to the wall, so it must be turned through 90 degrees to close. The door is 3.00 m tall and 1.25 m wide, and it weighs 750 N. You can ignore any friction. If Exena applies a force of 220 N at the edge of the door, what is the minimum time does it take her to close the door
