aight

hallo!

Bonjour, mademoisselle

Can you change the room topic to reflect that this is for your math & physics?

ooh, I remember this one

I'm not sure I'm even on the right track tbh

Kinda confused

which part are you on?

Are the first two parts correct?

I'm on part c, technically

the FBD (with dot) should show forces, not a & v

Ohh, right

Isn't it just straight up towards the middle?

Wait that makes no senses

It's down

are you talking about ball or astronaut?

The astronaut

the astronaut has just normal, to center, yes

So it is just up?

(also I am totally cheating and going off my teacher's video keys)

@PrinceNorthLæraðr yep

Oh lol

So wouldn't the ball to an observer from the outside look like a circle before hitting the floor...?

the ball would go left in a straight line, no acceleration

Why?

because it inherits the astronaut's velocity

but no forces act on it until it hits the ground

Oh, but not the normal force because it's not on the surface

yep, before hitting it has no normal

Ohh

makes sense?

So before it lands, only velocity, after it lands velocity+acc.

Yea

what direction would acceleration point?

Up

Bc centripetal acc.

Or sorry, towards the center

So up in this case

What direction would acceleration point, relative to how it is moving?

because it moves to the side before hitting the floor

so when it hits, "to the center" does not equal "up"

huh??

Okay let me think

My teacher explains this well, so I'm trying to just do it how she does

(don't want to link because that would give you my school)

It would travel the distance of the vectors or something right? Let me try to draw this

@bobble Makes sense

Oh, it travels perpendicular to the velocity

I drew the thing

what

Adding picture to show ball's path from when astronaut drops until it hits the floor

oh okay

Remember, you said velocity just goes left

So when it hits the floor, what direction will the acceleration be?

What direction will the velocity be?

@bobble No, you did :P

ah. sorry.

Lol

but you said it makes sense

so same difference

Yeah

So, a & v directions for after floor hit?

The velocity would still be to the left because the circle is still spinning clock-wise, but the acceleration would be uh tangental right?

what direction is the force?

Inwards

because normal force

so what direction is the acceleration? can you draw the v & a dot thingy?

Ohhh, I think I got it

I'll draw it

Something like this?

yep!

tangential velocity, inwards acceleration

Ah got it

Okay, gotta go, thanks for the help

see you :)
