This is part of my homework for an online physics class(they cut the teacher for it). I have to solve a problem, but even the "teacher" who watches us who is a science teacher doesn't know what to do. Can anyone help?

A robin is flying south for the winter at a rate of 40 mph when it runs into a hurricane, blowing due west at 100 mph. What is the new velocity of the robin?

Thanks

I am working on a homework problem in my high school physics class, and I'm stuck on a simple problem. Hopefully someone can help. Here's the question.

Ernie and Burt take off from the same point in their individual cars traveling in the same direction along a straight highway. Ernie travels at 75 miles/hour and Burt travels at 60 miles/hour. How much sooner does Ernie arrive at a destination 10 miles away. How far must Ernie travel before he has a 15 minute lead on Burt?

Thank you for the help!

I was reading on CNN.com about how a study dismissed the sun as a possiblity for global warming because it has not raised in temperature enough, for over 1000 years. I was wondering if maybe the sun could have possibly expanded over that time to increase temperatures on earth. I like to hear peoples thoughts about it. (I do feel though that people are inpart of the cause for the heat up issues).

U.S. HAS SECOND WARMEST SUMMER ON RECORD
Nation Experienced Warmest January - August Period On Record

Sept. 14, 2006 — Summer 2006 was the second warmest June-to-August period in the continental U.S. since records began in 1895, according to scientists at the NOAA National Climatic Data Center in Asheville, N.C. Additionally, the 2006 January-to-August period was the warmest on record for the continental U.S. Above-average rainfall last month in the central and southwestern U.S. improved drought conditions in some areas, but moderate-to-extreme drought continued to affect 40 percent of the country.
