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

Suppose you are standing uptight with your right arm stretched out straight in front of you, palm down, the upper arm rotating rightward relative to space at 2 radians/s and the elbow flexing in the horizontal plane at 2 radians/s. What is the rotational velocity of the forearm in space?

2. Relevant equations

3. The attempt at a solution

I am not sure if I understood the description of the movement correctly, because now I have the impression that there are informations missing I would need to solve this, e.g, on which point on the forearm the rotational velocity is measured, because I thuoght that would depent on the point on the forearm.
