## Homework Statement

## Homework Equations

I want to say I should be using this one:

**a**

_{A}=

**a**

_{B}+

**α**x

**r**

_{A/B}+

**ω**x (

**ω**x

**r**

_{A/B})

## The Attempt at a Solution

The only problem is that if I'm supposed to find the angular acceleration then i'd have to take the... inverse of the cross product? To get it back and I don't think that that's possible. I also want to say that it's zero because

**OQ**moves with constant angular velocity, but I believe that that would result in

**PQ**moving with acceleration because theta would be changing?
