Activity11.12.2.The Ferris Wheel.
You are riding on the top of a vertical Ferris Wheel with radius \(R\) and initial tangential velocity \(-v_i\text{.}\) The next time you are at the top of the Ferris wheel, your tangential velocity is \(-3v_i\text{.}\) Find the angular acceleration of the Ferris wheel.
