## Homework Statement

Please help!! This is my question!

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 8.00m every 5.00s and rises vertically at a rate of 3.00m/s .

a)Find the speed of the bird relative to the ground.

b)Find the magnitude of the bird's acceleration.

c)Find the direction of the bird's acceleration.

d)Find the angle between the bird's velocity vector and the horizontal.

## Homework Equations

I'm not to sure of the equations that I should really use as I am trying to re-learn all the math behind it! My guesses are:

a) a(rad) = v^2/R and stops from there...

## The Attempt at a Solution

I have made a diagram of what I think it should look like but thats about as far as my attempt goes... I am in need of some help and advice, My main problem is looking at the question and trying to decide what equation will give me the right answer. Please help!
