. 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 2.95 s. How long does it take door B (also starting from rest) to rotate through 90 degrees? Xs Axis Door A Axis Door B
