Well I searched and I found this answer for the second question in this link United States GDP Annual Growth Rate | 1948-2015 | Data | Chart | Calendar (http://www.tradingeconomics.com/united-states/gdp-growth-annual) and the answer is:

The Gross Domestic Product (GDP) in the United States expanded 2 percent in the third quarter of 2015 over the same quarter of the previous year. GDP Annual Growth Rate in the United States averaged 3.22 percent from 1948 until 2015, reaching an all time high of 13.40 percent in the fourth quarter of 1950 and a record low of -4.10 percent in the second quarter of 2009. GDP Annual Growth Rate in the United States is reported by the U.S. Bureau of Economic Analysis.


But I didn't find anything for the first question..

Well I don't study the economy in U.S
The professor gave each group a different country and told us to find the answer for these two questions, so I don't have any notes about that..
And I'm sorry if I'm bothering you guys..

You aren't bothering us at all. We are just here to help you. We can't give you the answers outright.

Tell us us what you think the answers are, that way we can guide you in the right direction.

What you need to learn to do is research using the web. Programs like Google allow you to plug your search in and find the answer
