Aye Q5 multi choice asks which has the greatest travel time yeah. And all the intervals are equal distance. And if velocity is greater at larger radii then the “greatest travel time” would be the lowest velocity coz t = d/v … so ain’t the answer B (not D)

what we getting for q 19 and 20 mc

Radius -10 and height 4… about the y axis. Made this mistake in the exam rip

pretty sure q is either 1944 or 80 (not 81 or 1943) coz u gotta add one/ subtract one by the n-1 identity

pretty sure that q was pi(1200 +600ln1/3)

looks like q 8 is A

C, A

yeah i agree, it was kinda fricked

@pdawg only 67? bro im thinking i got like 68 or 69

i think i got -1/3 but idk if its the negative or positive reciprocal of 3 i forgot

can we all agree? 1) D 2) A 3) C 4) C 5) B 6) C 7) B

someone share solutions @carrotsss this is ur time to shine bruh

aye anyone get q5? c right?

the r(t) function is for both up and down coz its displacement from origin, not dist covered

let r(t) in y comp = zero and hence this is equal to zero then you get like 9/4t = 1-e^-4t meaning its where the two graphs intersect... then substitute t = 2.25 into r(t) horizontal component

yall know how on earth to do 15b ii?

let r(t) in y comp = 0

yeah bro 8.7 m for 13c iv

and then the final part to that question > the proof didnt work coz i used their incorrect thing from part ii

thats what im saying bro i thought i was tripping
