a.)Find the angular momentum of this brick about a horizontal axis through the fulcrum and perpendicular to the plane of the figure the instant the brick is released.

b.)Find the angular momentum of this brick about a horizontal axis through the fulcrum and perpendicular to the plane of the figure the instant before it strikes the seesaw.

**anoymous student**, Wednesday, July 27, 2011 at 2:32amthe answer to part a) is zero. I don't know why right now though. and the answer to part b) would be 45.1 if it was a 4.50kg brick. I also don't remember how I got that answer.

**anon**, Monday, March 11, 2013 at 4:40pmFor part B:

angular momentum =

m*r*sqrt(2gh), where r=1.6 and h=2

5*1.6*sqrt(2*9.8*2)
