Exercise 1:
On April 15, 1912, the luxury cruiseliner Titanic sank after running into an

the iceberg if it had hit the iceberg head-on with a speed of 11.6 m/s? (Actually,

iceberg a kilometer ahead and had tried to slow down, why would this have
been a futile effort? (Read more about the Titanic at http://www. titanic. com)
