A MODU displacing 29,500 long tons has a KG of 60 feet. A weight of 500 long tons is added at a VCG of 150 feet. What is the change in KG?

A 2.5 feet upward
B 2.0 feet upward
C 1.5 feet upward
D 1.0 foot upward
AI Explanation

The correct answer is C) 1.5 feet upward. To calculate the change in KG, we can use the formula: KG_new = (KG_old * Displacement_old + VCG_new * Weight_added) / (Displacement_old + Weight_added). Given: - MODU displacement: 29,500 long tons - Original KG: 60 feet - Added weight: 500 long tons - VCG of added weight: 150 feet Plugging in the values, we get: KG_new = (60 * 29,500 + 150 * 500) / (29,500 + 500) = 61.5 feet The change in KG is the difference between the new KG and the original KG, which is 1.5 feet upward. This makes option C the correct answer. The other options are incorrect because they do not accurately reflect the change in KG based on the given information.
