(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Birds of prey rise up and down on thermals. A bird completes circle of radius 8m every 5s and rises vertically at a rate of 3.0 m/s. Assume uniform acceleration. Find

a)speed of bird relative to ground

b)magnitude of acceleration

c)direction of birds acceleration

d)angle between birds velocity vector and horizontal.

2. Relevant equations

a_{r}=V^2/R

3. The attempt at a solution

I have found the answer to a be 10.5 m/s, the answer to b is 12.6 m/s^2

c)a_{t}/a_{r}=tan^-1(3/12.6)=13.3 degrees

d) I'm not sure how to proceed for this equation.

Any help is greatly appreciated and thank you for your time.
