Fuck you

>50 cm radius fidget spinner
Brainlets aren't welcome here

>>8931969
Who says they don't exist?

>>8931965
Yes

>>8931965
what color is it?

>>8931965
30 degrees relative to what?

>>8931965
zero

>>8931965
>It has a radius of 50 centimeters

>radius
>not a circle
what did he mean by this?

It doesn't have to be a circle

>>8931965
that's a big spinner.

>>8932165
zero

Uuuuuuu

>>8932429
All of those have circular sections.

>>8931965
does it matter how far from the centre of the rotation the force is applied?

>>8931965
Is there a constant force of 10N for the full 3 seconds?

>>8931965
How much does the spinner weight you dumb fuck?

Is this happening on earth or any other planet? Or in a vac?

What type of material is the spinner made of?

What is its 3d model?

Sure, but they dont rotate about those circular sections.

A propeller is not a circle, but it has a radius about which it rotates.

Do you really need to ask this....? Like you're gonna calculate air resistance?

We do need to know the moment of inertia though.

>>8931965
Zero, the fingers get in the way.

Its called a ceiling fan when its that size.

How long is the force applied for?

>>8931965
A fidget spinner is topologically equivalent to your mom.

Denote as the sum of the natural numbers is [math]-\frac{1}{12}[/math] it does 69 rotations in 420 seconds. q e d

[math]rF\sin(\alpha)=J \ddot{\theta}[/math]

I guess it barely rotates given the large magnitude of lamina.

It rotated for 0.0358 of a revolution or 0.225 rad if I didn't screw up like I always did in my homework.

need more info
we don't even have mass

>its rotational inertia is equal to 50 kgm^2.
close enough

A rattleback is placed next to a fidget spinner.

Both objects are set into a typical motion.

What will happen?
