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?
Homework Equations
radial acceleration = -rw^2
tangential acceleration = r*alpha
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
