Tangential acceleration - unknown term

1. Homework Statement

A man walks steadily outwards on a turntable (radius r) with radial velocity v. The turntable rotates with angular velocity w and angular acceleration alpha (anti-clockwise). What is the tangential component of acceleration?

2. Homework Equations

radial acceleration = -rw^2
tangential acceleration = r*alpha

3. The Attempt at a Solution

The answer given for the tangential acceleration is (r*alpha)+(2wv)
I understand the r*alpha bit, but could someone please enlighten me as to what the 2wv part refers to?

Thanks very much

Have you learned about Coriolis force?
 
I thought that Coriolis was where an object appeared to deviate from its path. How is it related to this problem?
