re: angular momentum & parallel axis theorem... great! thanks for that. re: energy methods... that was the first approach I took, which seemed so clean and tidy, but when you think about this physically, if you impact the easel near the top rather than near the bottom, the applied moment is...

thanks for the notes... sorry, I meant conservation of energy (KE/PE for whole system)... I was barking up the wrong tree there though... I'm going to give this a try using the angular momentum format suggested... one question though... Do I need to use the same axis of rotation for the...

I have a problem that I'm having trouble cracking and was wondering if anybody has any ideas on it. An impact test that we have to do involves swinging a pendulum of weight 50lbs into a rolling easel (for writing on, approximately 6ft high, with casters). The wheels are blocked so the easel...
