Question
A small 5.00 kg brick is released from rest 3.00 m above a horizontal seesaw on a fulcrum at its center, with a radius of 1.60 m. 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. Then, 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.
Answers
What progress and effort have you made on this? Is the brick really released above or on the fulcrum, as the problem states? The instant the brick is released, there is no momentum.
