On April 15, 1912, the luxury cruise liner Titanic sank after running into an iceberg. A)what momentum would the 4.23 X 10^8- kg ship have imparted to the iceberg if it had hit the iceberg head on with a speed of 11.6 m/s? (Actually, the impact was a glancing blow). B) if the captain of the ship had seen the iceberg a kilometer ahead and tried to slow down, why would this have been a futile effort?
