Curious if this is right

L=Iw

Both are point masses so I=MR^2, so I

=(4KG)(.5M^2) + (3KG)(.5^2)

w=r/v

w=.5/5 = 1/10

So plug this all back into L=IW

[(4KG)(.5M^2)+(3KG)(.5M^2)]x.1

One slight change.

[tex]v=r\omega[/tex]

so:

[tex]\frac{v}{r}=\omega[/tex]

[tex]v=r\omega[/tex]

so:

[tex]\frac{v}{r}=\omega[/tex]

Ah so its 5/.5 so 10, thanks!
