(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

please see attached picture.

2. Relevant equations

a(sub b)=a (sub a) + a (sub b/a)n + a (sub b/a)t

a (sub b/a)n=0 b/c originally at rest

a(sub b)=r(sub b)*alpha(b)

therefore:

r(sub b)*alpha(b)=a(sub a to the right) + 6*alpha(sub ab to 45 degrees, right up)

x direction: 1m*alpha(sub b)=10+6alpha(ab)cos45

y direction: 0=0+6alpha(sub b)*sin(45)

alpha(ab)=0; alpha(sub b)=10 rad/s^2

sum of moments (clockwise positive)

=-2g(3sin(45))+10(6sin(45))=I(sub G)*alpha(sub ab)+ma(sub G)*3sin(45)

a(sub G,ab)=0.19m/s^2 to the right

3. The attempt at a solution

is this right? it seems tooooo easy. thanks ahead of time!
