🔍 Key Concepts

• Use the rolling period formula that relates beam (B), metacentric height (GM), and rolling period (T) • Remember that a larger GM usually means a shorter, snappier roll period • Be sure you are using the correct constant for the empirical rolling-period formula used on USCG exams

💭 Think About

• First, write down the standard empirical formula used to estimate rolling period in seconds from beam in feet and GM in feet • Plug in B = 50 ft and GM = 4 ft, paying attention to whether GM is under a square root in the formula • After calculating, compare your numerical result with the answer choices and pick the one that is closest

✅ Before You Answer

• Confirm that the formula you use has T directly proportional to beam (B) • Confirm that GM is in the denominator and under a square root in the formula you use • Double-check your calculator work and units so your result is in seconds and then compare it carefully to the four choices
