Re: When Physical Intuition Fails

No apologies necessary!  But, I did not use conservation of momentum
(angular or otherwise).  I simply set up the force and torque equations and
integrated.  You have to be careful, since forces and torques are not
constant -- but it's still not too difficult to integrate.
