Homework Statement
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.
Homework Equations
ar=V^2/R
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)at/ar=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.
