# Homework Help: Rotating tube with particle inside

Ok so I have this tube of length 2R that rotates in the horizontal xy plane with constant angular velocity $$\omega$$ about the z axis. And there is this particle of mass m that is released a distance R from the origin. Assuming the tube is frictionless I need to find the direction of the velocity of the particle just as it leaves the tube?

Any help is appreciated!
