Answer:
the length of the bridge B is L = m - 5555 ft
Explanation:
Denoting the length of the bridge B as L we get
length of bridge B = length of bridge A - 5555 ft
since length of bridge A=m
L = m - 5555 ft

Answer:
infinite
Explanation:
The tangent of the angle the arm makes with the vertical will be the ratio of the centripetal acceleration to the acceleration due to gravity on the center of mass of the arm. The angle can only be 90° (fully-open arms) if that ratio is infinite.
The speed must be infinite for the arms to be fully open.
