Two doors both have mass 50 kg and width 2 m. Door A rotates
around hinges through its left edge, and door B is a revolving door
that rotates about an axis through its center. The same force F is
applied perpendicular to each door at its right edge and are kept
perpendicular to the doors as they turn. Starting from rest, door A
rotates through 90 degrees in 2.75 s. How long does it take door B
(also starting from rest) to rotate through 90 degrees?
