# Non-Uniform Circular Motion - Finding total acceleration

## Homework Equations

Code:
a(total) = sqrt( a(tangential)^2 + a(radial)^2 )

## The Attempt at a Solution

I wrote out equations for the forces in the radial and tangential directions:
Code:
F(radial)       = T - ( mg * cos(θ) )
F(tangential) = mg * sin(θ)
I used the equations to find acceleration in the radial and tangential direction (a = F/m):
Code:
a(radial)       = (T/m) - ( g * cos(θ) )
a(tangential) = g * sin(θ)
I plugged it into a(total) = sqrt( a(tangential)^2 + a(radial)^2 ):

which simplifies to:

My answer is incorrect and I'm not sure what I did wrong.
Any help would be appreciated.
