Example: Knock Nevis was the world's largest supertanker with a length of 485 m and a depth of 30m. It was made from steel (density 8050 kg m-3) with an average hull thickness of 3 cm Approximating it as a half cylinder what is the maximum possible mass it could carry before it sinks? Knock Nevis was rated to carry up to 565,000 tonnes (1 tonne - 1000 kg). How much of it would be underwater with this cargo?
Example:...

A solid cylinder of radius 10 cm and mass 13 kg starts from rest and rolls without slipping a distance of 6.0 m down a house roof that is inclined at 30°. (See the figure.) What is the angular speed of the cylinder about its center as it leaves the house roof? The outside wall of the house is 5 m high. How far from the edge of the roof does the cylinder hit the level ground?
