Homework Statement
Hi, I was wondering what is the difference between the equations an=w^2 x R vs an=V^2 / R? I thought both of these equations were the same? What is the normal acceleration at C and D?

an=w^2 x R vs an=V^2 / R?
The Attempt at a Solution
[/B]
If I use the equation w^2 R for the normal component
At point C I get (16)^2 x (0.25) = 64ms-2
At point D I get (16)^2 x (0.25) = 64ms-2
However, if I use the equation v^2 / R for the normal component
At point C I get (6)^2 / (0.25) = 144ms-2
At point D I get (2)^2 / (0.25) = 16ms-2
Why is this so?
