I might have messed up with finding acceleration or something

It is a pretty easy question. Sorry i couldn't get to it earlier. Did you follow similar steps like i did? 👀

I put it as -7m/s/s

well I converted it to kg but don't know what you got for friction

you judge the force in the x-direction

since the puck is sliding on its own with no applied force, only friction is acting on it

I"m pretty sure the only force acting on it the friction and it's moving constantly so the final velocity should be 0

this is the steps I did

i quickly calculated it out. a-value is about -7.85 m/s2. so you should be good

looks right to me 👀

I was skeptic with the 192m but forgot it's a hockey stick

although i personally wouldn't find the time

it's an extra step that can mess up

oh I don't know how to find it without time

i'd use this equation:

I don't know how far it goes though

I assume x is distance

that's what you're finding

yes, x is the distance

the question asks for how far it will slide, no?

or could I isolate x and have it vi^2 - v^2 + 2a = x

v-final is just 0

wait, no vf^2-Vi^2/2a = x

idk if my algerbra is right but I think that's how it goes

he said I would learn it in grade 12 so

lmao yeah (vf^2 - v0^2) / 2a = x

it's simple algebra lmao. you just move the pieaces around

well I don't know how this works and he just gave us the standard v = at

just googled kinematic equations

i can give you my physics formula sheet

Ew. Physics.

same girl <:KEK:795742276549607456>

eh I don't think I need anything more than that. Will keep it in hand

also punched it in and got the same answer huh

I passed the class and test, but it was still awful. 😂

so what other formula sheets are there?

dude my physics teacher sucks so much

that's why I didn't bother and was like "well crap"

well, mine is cleaner, and includes everything you need

yea sure, I'll take a screenshot and write them down
