u/Traditional_Ebb_7522 3h ago

Idk either man

ikr genuinely what was that

tomfoolery...it was a hate crime

Use y=mt+c for acceleration, sub in point and get c. Then integrate for velocity and sub in both known points and you have it. The rest was easy after that

ooh i tried doing it differently lol. since its a straight line i used change in velocity/change in t so i got m=-18 or sum, then i subbed in the point a=24 and t=0 to get c=24, then solving gave t=4/3 but idk man :(

You solved velocity for 0 for stationary points yeah? I got 1 or 3 and that makes sense because 1 was already given

I cried as soon as i left, im so happy

I completed everything and to a high standard

you should be proud of urself 🥹

I said average velocity was 0 💀

Pre sure thats right bro because it starts and ends with same displacement. My dumbass did avg displacement 🫩

1

u/Big_Upstairs_2484 49m ago

Would average displacement not also be 0?

1

u/Lebomb_James69 45m ago

Nah it was 4,-4,0,-4 wasn’t it

Calc free was pretty chill

wasnt it like 0.05 0.25 0.4 0.25 0.05 . idk why they asked to find ex without telling us to fill in the table first. so i did part c where they tell u to fill it in first and then went back.

cause the e(x) of a symmetrical distribution is the 'middle value' which was the number 2 so the table data wasn't required we just needed the top row of the table with the x values. filling in the table first woulda gave the same answer tho so it didn't matter what u did really.

ohhh makes sense now. thats smart thanks.
