#### Solution Preview

Please see the attached file.

We have a case of centripetal motion, thus the velocity can be found from v2 = a r where a is the acceleration and r is the radius of the circular path. See the figure.

We can calculate the acceleration from Newton's law of motion. F = m a. The various forces ...
