**Calculate angular momentum? I almost got the right answer but it's wrong!! Help!**

This is what I did for part a...

1. What is given

__Particle__

m

_{p}= 0.450 kg

ω = 2.00 rad/s

r = 1 m

__Stick__

m

_{s}= 0.125 kg

ω = 2.00 rad/s

r = 0.5 m

2. Angular momentum is conserved (L

_{initial}= L

_{final}) due to a lack of friction

0 = L

_{final}

L = Iω

L = (mr

^{2})ω

L = (0.450 + 0.125)(0.5

^{2})(2)

L = (0.575)(0.25)(2)

L = 0.2875

Help!!!!
