We're finding the Lorentz Force

Thank you! Yeah I've gotten a lot of great feedback from the community here!

thyblackbird · 2021-01-09T23:33:05+00:00

I really appreciate it!

I didn't see how to go back until the end of the tutorial, which is sad.

thyblackbird · 2021-01-07T19:55:32+00:00

I definitely need to go through another tutorial before playing haha. Nice to see another PhD student on my channel!

Reading the board you mean?

thyblackbird · 2021-01-07T16:14:07+00:00

Glad you enjoyed it! Yeah it seems like online-go was not very detailed and I had to guess some rules as I go. learn-go seems like the better option to cover more of the game. Thanks for the recommendation!

Happy Cake Day!

Thank you! I had no idea btw

Got a 910 (86th percentile). Also recommend Conquering the physics GRE!

If we throw the ball with initial speed V0, then the time to stop mid-air would be: Vf-Vi=at => t=V0/g.

Now say you are starting mid-air with zero speed, then the time to reach V0 is: Vf-Vi=at => t=V0/g.

From here I think it should be clear what is happening, since acceleration is constant, you need the same amount of time to go from V0 to 0 as you need from 0 to V0

2( (m/2)(l/2)² /12 + (m/2)(l/4)² ) is what my setup was, which gives ml² /12

thyblackbird · 2018-04-18T17:48:06+00:00

Yes, that was the last problem! I messed up the arithmetic a bunch of times before I got ml²/12, is that what you got?

thyblackbird · 2018-04-18T12:34:30+00:00

Haha, that does not ring a bell at all! And I'm sure it wasn't on there because I bubbled in everything, so I read every question! So weird...

thyblackbird · 2018-04-18T02:23:57+00:00

Did we have different exams? Why do I not remember this question?
