September 2014 PUZZLE - "Faster than g?"
Submitted by Dave Thomas
A hinged rod of length L is held at rest at an angle θ, and then released. At precisely the same moment, a steel ball is released from the same height as the top of the rod.
The September Bonus:If vrod is the speed of the tip of the rod as it hits the flat table top, and vff is the speed of the free-falling steel ball as it impacts the same table top, what is the ratio of vrod to vff ?
