Sequel to sliding puck problem. If you haven't yet figured out part I, that would be a good place to start. I've also posted another challenge in case people are tired of the sphere. What if, instead of a sliding point-mass puck, we roll an object down the sphere? Object rolls without slipping and has given moment of inertia.

So tonight I received an e-mail from my friend with a link to this cartoon, asking "is this true?" What do I tell her?

Here's a problem I encountered sometime in the first few weeks of mechanics last semester. Post an answer if you get one, or ideas if you have them. I can provide hints as necessary (diagrams, possibly useful tools, etc.) maybe starting later in the week. At this point I am considering turning these around on a weekly basis, and so I'll probably post a solution Monday, 12/6. If Mr. Fullerton wants to give extra credit for such things, I imagine one would want to have it done before then for extra points. And show all work! Whether by beautiful here or by mailing be the back of a napkin, documenting your thinking is imperative. Suppose a hockey puck sits atop a…

IRONDEQUOIT, Nov. 1, 2010 -- Students in physics classes taught by Dan Fullerton and Mike Powlin at Irondequoit High School were outside most of the day Friday, Oct. 29, testing the catapults they built by applying physics principles and concepts. Teams of students launched softballs from their catapults on the school's track, then measured their projectiles' range and time in the air. Based on those measurements, students will then apply their physics principles to calculate maximum projectile height, launch velocity and launch angle. The event was the first of a series of four "championship of physics" competitions during the current school year. [ATTACH=CONFI…
