Question

Find the angular momentum of this brick abouta horizontal axis through the fulcrum and perpendicular to theplane of the figure the instant before it strikes the seesaw. Find the angular momentum of this brick abouta horizontal axis through the fulcrum and perpendicular to theplane of the figure the instant before it strikes the seesaw. A small 4.50 kg brick is released from rest 2.50 m above a horizontal seesaw on a fulcrum at itscenter, as shown in the figure below . Find the angular momentum of this brick abouta horizontal axis through the fulcrum and perpendicular to theplane of the figure the instant before it strikes the seesaw.

Explanation / Answer

I think it is simply zero since it is released from rest. soits velocity is zero at the time it is released. L = m*v*r = 4.5*0*1.6 = 0
