Question

(a)  Cynthia is in a boat heading due east at 15 m/s and is reading a book.  She then finishes the book and throws her book off the back of the boat at a speed of 6 m/s due west.  What is the boat’s speed after Cynthia throws the book if the book as a mass of 4 kg and Cynthia and the boat combined have a mass of 700 kg?

(b)  To demonstrate your ability to carry out deductive reasoning in the context of PC 141, determine the how the velocity of the boat after Cynthia throws the book would change if the book’s mass triples. Does your answer in question #2 above seem reasonable?  Briefly explain why or why not?
