A light, rigid rod 1 meter in length roatets about an axis perpendicular to its length and its center. Two particles of masses 4 KG and 3 KG are connected to the ends of the rod. What is the angular momentum of the system if the speeds of earch particle is 5 m /s(adsbygoogle = window.adsbygoogle || []).push({});

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
