## Homework Statement

It is common to see birds of prey rising upward on thermals. The paths they take may be spiral-like. You can model the spiral motion as uniform circular motion combined with a constant upward velocity. Assume a bird completes a circle of radius 8.00 {\rm m} every 5.00 {\rm s} and rises vertically at a rate of 3.00 {\rm m/s}.

## Homework Equations

Find the direction of the bird's acceleration.

## The Attempt at a Solution

I found the bird's acceleration to be 12.6m/s^2

But I have no idea how to find it's direction. It's being asked for as an angle.
