Problem with diagram here
I=(1/3)MR2 (I believe the formula given in the problem is incorrect since it is pivoting on one end rather than the center of mass)
The Attempt at a Solution
True, the velocity is still going in the same direction at the instant of the collision.
False, it is a perfectly inelastic collision, which means kinetic energy is not conserved.
True, no real reason why. I just think it's true? No forces seem to be working on the center of mass during the collision.
True, no external forces/torque are working on the collision at that moment.
I have no idea how to approach this correctly other than the possible use of the parallel axis theorem. This was as far as I got
The answer is given: (5/6)MgL+(1/12)Mv2
Can someone please explain to me the steps to get to that answer?
