This question has me absolutely stumped, I have no idea what to do

I see you go to Maribyrnong college.

I hope your professor enjoys your obvious cheating during a test.

This board should prevent Australian IPs from posting, there has never been a notable Scientist or Mathematician from OZ, nor will there ever be, unless one comes up with a clever way to kill off all the giant poisonous spiders and snakes there.

That guy who won a nobel prize in Physics

Dont turn v into dr/dt, turn a into dv/dt

>> No.6102005

change a = .9mgv^2 to dv/dt = .9mgv^2 and you can solve the differential equation

You fucking kidding me? Terence Tao has a fields medal, and he's one of the most famous mathematicians alive today.

Ah ok this anon knows what he's talking about.

Wow what a fucking retard.

dude, its a paper that any school in Victoria can obtain, you really think you've pin pointed one out of hundreds of schools?

Alternately, use the identity a = dv/dt = v dv/dx. That way you can neglect time entirely.

But that doesn't help if you have GPS enabled on the exif file of your phone camera pictures

I don't think you've set up the problem correctly, it should be something along the lines
Fnet = mg - .09mgv^2
Fnet = mg( 1 - .09v^2)

>> No.6102026

>>6101999
Yeah, because most of the other posters on /sci/ are notable scientists and mathematicians. Clearly its just we Australians bringing the board down. Keep up the quality amirite?

The majority of posters here are undergraduates, not notable scientists. As someone who has actually published a few papers (and even got some meagre citations) I'd say I'm probably among the most notable we've got. That alone probably puts Australia towards the top of 'notability' of /sci/ posters.

>> No.6102030

lol so much if OP fails specialist maths because of this thread in like the last week of yr 12.

But since he can't even do this question its not like he would have gotten above 35 anyway
