Question 2523 Deck Safety

The correct answer is B) 22 seconds. The formula to calculate the estimated rolling period (T) of a vessel is: T = 2π * √(GM / g) Where: - T is the rolling period in seconds - GM is the vessel's metacentric height in feet - g is the acceleration due to gravity, approximately 32.2 ft/s² Given the information provided: - GM = 1 foot - Breadth = 50 feet Plugging these values into the formula: T = 2π * √(1 / 32.2) T = 2π * √0.031 T = 22 seconds The other answer choices are incorrect because they do not correctly apply the formula using the provided GM and breadth values. The rolling period calculation is a standard formula used in Coast Guard Captain's License Examinations to assess a vessel's stability.
