Q6 projectile was too easy (1 Viewer)

[peeasoup]

For a question 6 projectilce question, it was fucking easy. Who agrees....?

 

[smallcattle]

i wont agree i wont i wont i wont

 

[fush]

yea it was pretty straight forward..even though i know i lost 2 marks for it

 

[mishka]

not me!! i hate projectile motion and sat there confusing myself. ended up coming up with some answer i KNOW is wrong!!

 

[Shuter]

there was one part I couldn't quite get out I think but otherwise yeah easy as hell.

 

[grimreaper]

I think it was fair for a q6 - if it had been in q7 it would have been to easy

 

[Sweet_Lemon]

tat one wasn't bad...hey..if that's the last question...i'd love tat~~ stoopid 3 unit!

 

[absolution*]

did anyone else get two answers for the final part. like 45 degrees and 71 degrees. i wsnt sure to i just put between 15 degrees and 45 degrees.

It wasnt easy, but it was pretty straight forward.

there are 2 ranges for theta. 15<theta<45 is one, but the other was larger 71<theta<somehitng

 

[peeasoup]

I said between 45 and 71

shutup you fool. you didnt even read the q. it wanted the rnages of theta to hit the wall. not not make it over. it is between 15 and 45 and there is another range above 71 to something

 

[mojako]

15 < @ < 45 (degrees)
OR
inverse tan 3 < @ < 75

 

[becany]

yeh i got values of theta as 45 and 71...BUT i didnt put it was in between! doesnt it say just hit the wall? not over, or under, or whatever?

 

[bevstarrunner]

15º to 45º, 71º34' (ish) to 75º

well it says the front part of the wall.
so at x=40,
0 < y < 20

 

[the_13th_falcon]

Boys and girls...it just clears the top of the wall at 45 and 71 degrees. but at 71 degrees the water is falling. at 45 degrees it just reaches horizontal. so make the angle 46 degrees and it clears the wall...same for 45 through to 71 degrees. misses bottom at 15 degrees. anything above 15 and below 45 degrees hits wall. 15<theta<45...thats it

 

[LMF^^]

Mate I aced the whole thing.
WoOoOoOoOoooO
Now time to chuck a shit.

 

[layzeee student]

fuk u geeks stop worrying about a stupid exam. how easy was it like seriously. 84/84 for sure + no study
fuk yeh LMF good idea, i need to chuck a shit too

 

[senso]

i only did the very first part of the projectile motion because of time, and aced it.
But it was good to see something easy in such an otherwise hard test
