16. The true size of the iceberg that sank the Titanic may never be known. Let's hypothesize its size using what we know. Eyewitnesses estimate the iceberg was between 50 m and 100 m above water and 200-400 feet in length. We will split the difference and assume 75 m above water and the iceberg is a square pyramid with length & width 300 m ( V = " ). Use gig =910 kg/m & @seawater = 1025 kg/m'. a. What is the buoyant force acting on the iceberg? b. How big do you estimate in volume was the iceberg that sank the Titanic? BONUS QUESTION: What might have been the mass of the iceberg
