1. The problem statement, all variables and given/known data
I have a test in the morning. Here is a link to the website where a practice test is located. http://www.mc.maricopa.edu/~vantassell/PHY121/phy121.html [Broken]. It is on the left under sample test 1.

2. Relevant equations
The relevant equations are at the bottom of the test.

3. The attempt at a solution
1.D
2.C
3.D
4.A
5.B
6.D
7.D,A,C,F,B,E
8.E,D,C,A,B,F
9.Skip
10.Skip
Calculations
1. mag=sqrt(106.9) theta= 228 degrees
2.91.5 m/s
3. 29m/s
4.a.87.5m b.32.5s
5. no
6.a 285m b.236.4m c. 9.5 m/s d.-7.9m/s

I rounded a lot of the answers. If someone has time, could you see if my answers are correct? Thanks

If no one has time for the entire practice exam, maybe someone could check the first 8 multiple choice conceptual questions? That would help a lot.

I, along with many other homework helpers, am not going to open a .doc file from a university website. Repeat those questions for which you are unsure of your answers.

In general, you are much more likely to get help from people at this site if you
• Make it easy on us. Put the question in the post. Expecting us to open some potentially virus-infected .doc file just to see the question is not making things easy on us.
• Show some work.
• Keep the post limited in scope. Which problems are you specifically having problems solving?
