A point mass m rotates with an angular velocity omega around a rotation axis, which in turn rotates with angular velocity Omega in the same direction around a second axis (see figure). Identify the point where the absolute speed of the mass m assumes the minimum value and calculate the absolute speed and acceleration values at that point.
I know from relative motion that $v = v'+v_{O \ '}+ \Omega \times r'$
I our case $v = v' + \omega \times r'$ where $v'$ is velocity of mass m in the rotational system and $r'$ is position of mass in the rotational …
