I wanna learn vectors now That looks fun. If I've done mex1 for the year 11 syllabus I should be fine right?

mmm
you've done physics tho so yeah

isn't vectors in phys really different to the math version

 

[aaliya]

im dead you guys are actually trying to help him

fr fr like he is such a pmo like coolcat ykwim guys

 

[Flatuitous]

isn't vectors in phys really different to the math version

well the math vectors are more mathy and the physics vectors are less mathy
so ig so

 

[Flatuitous]

same physical concepts right? Just that math vectors are more complex?

yes
physics is very rudimentary

 

[f7eeting]

i dont really know how to approach this question, any help would be appreciated

PHYSICS QUESTION

can you give me some physics wisdom to help with this question

 

[Flatuitous]

Correct me if I'm supposed to use some crazy ext strats or something insane like that

nope this is most definitely a physics type of question so u can do it with just physics methods

 

[f7eeting]

this is what the worked answers looked like... i had the exact same diagram as what you did but the worked answers seem to be doing something different
(to be fair though this is the last answer of the ext 1 hsc so it makes sense its pretty hard)

oh you do need ext1 methods?
hm it seemed like a physics typa q

 

[f7eeting]

I finally understand whats going on wth.

please elaborate, i still dont get it

 

[Study to success]

yeah nah thats cooked bye bye

yeah ur physics method looked just like normal trig. bro why do they have to overcomplicate it in ext

[Jaros]

Omdz I've just forgotten exact values exist in trig..... By any chance could it be something wrong with the answer given to the question? I would think otherwise but most the answers we get are 1-2 degrees off so it cannot be anything big thats wrong?

I dont see a problem with how u or I did it, I think its becoz the answer approximated to 60 degrees maybe?

 

[Jaros]

nah that can't be, cuz I did 60 degrees and the answer would increase I checked

 

[CirrusTheJet]

I will have a go at the problem, then I will have a better look at your method. I think so far it looks correct though.

 

[CirrusTheJet]

Clearly I did something wrong

 

[CirrusTheJet]

Incomplete approach which got too complicated. I might just continue with this approach and see how it turns out.

 

[CirrusTheJet]

Ignore the wrong v+w thing.

what tf would my answer be even be accepted, I didn't even attempt to do allat working out and kinda stuck to resolving vectors? so is my answer still valid?
