A*R*C*S 11.12.1. The Motion of Mars.

A year on the planet Mars has been observed to be about 687 Earth days long. Starting from a free-body diagram, determine the orbital radius of Mars.

Activity 11.12.2. 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.
