Has anyone done 2008 F=ma contest?

[maruhan2]

I've been practicing for 2009 F=ma contest (Physics Olympiad preliminary test) by doing 2008 test but the last 10 problems are TOUGH
I couldn't solve any of them correctly
Can anyone help me with them?

Try posting individual problems and your attempt at solving them in the appropriate forum in the "Homework and Coursework Help" section. One problem per thread, please, and it's probably a good idea to focus on one problem at a time instead of trying to do several at once.

I am not sure if anyone has specifically done the 2008 F=ma contest, but there are likely people who have participated in previous years' contests and can offer advice and tips for preparing for the 2009 contest. The last 10 problems being tough is not uncommon in physics competitions, as they are designed to challenge and push students' understanding and problem-solving skills. My suggestion would be to continue practicing and seeking help from others, whether it be through online forums or reaching out to past participants. Keep in mind that while it may be discouraging to not have solved any of the last 10 problems, the important thing is to learn from them and use that knowledge to improve for future competitions. Best of luck with your preparation for the 2009 F=ma contest!
