Question

I need some quick help with linear velocity! I want you to work it out with me, DON'T JUST GIVE ANSWER.

Question attached in comments.

Answer 1

there is a relation between linear and angular velocity which I cant remember...

Answer 2

first, you have to convert revs per second to rad/sec

Answer 3

Okay, so determine angular displacement first?

Answer 4

angular velocity

Answer 5

Okay, one sec.

Answer 6

16pi rev/1sec

Answer 7

16pi rad/ 1 sec i mean

Answer 8

Is that it?

Answer 9

I'm sorry, I'm honestly lost...

Answer 10

sorry i was called away
yes thats right 8 * 2pi

Answer 11

I'll check out that formula.
16pi because there's 2pi radians in one revolution

Answer 12

Okay, I mean, I already know the radius, which is 15cm, and I have to end up translating cm to m, and rev to velocity.

Answer 13

yes - oh its simply v = r w where ww = angular velocity

Answer 14

* w

Answer 15

I have so much trouble setting up dimensional analysis.

Okay, so I think I might have it.

15cm * (1/100) * 16pi

7.54

Answer 16

correct

Answer 17

Thank you so much!

Answer 18
