Buoyancy Homework

1. On April 15, 1912 the Titanic sank on its maiden voyage when an iceberg ripped a hole in the side of the ship filling five of the interior compartments with water. Use buoyant force to explain how the Titanic floated in water but then sank as it filled with water.

2. An object that weighs 340 Newtons floats on a lake. What is the weight of the displaced water? What is the buoyant force?

3. Look at the cartoon to the right. Use buoyant force to explain why the duck is floating lower in the water than the other ducks.

***Find the cartoon on the bottom of the "notes" handout that I gave you in class today. It shows four ducks and one is floating deeper in the water than the other ducks.
