The figure shows the cross section of a garage door which is a uniform rectangular panel 7.3 ft by 7.3 ft and weighing 236 lb. The door carries two spring assemblies, one on each side of the door, like the one shown. Each spring has a stiffness of 71 Ib/ft and is unstretched when the door is in the open position shown. If the door is released from rest in this position, calculate the velocity of the edge at A as it strikes the garage floor. wwwww Owwww B 7.3' 9.2' 7.3' Answer: VA i ft/sec
