Question

While exploring a castle, Exena the Exterminator is spotted by a dragon who 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 90.0 to close. The door is 3.00 m tall and 1.05 m wide, and it weighs 725 N . You can ignore the friction at the hinges.If Exena applies a force of 205 N at the edge of the door and perpendicular to it, how much time does it take her to close the door?
