Ahockey stick of mass ms and length l is at rest on the ice (which is assumed to be frictionless). a puck with mass mp hits the stick a distance d from the middle of the stick. before the collision, the puck was moving with speed v0 in a direction perpendicular to the stick, as indicated in the figure. the collision is completely inelastic, and the puck remains attached to the stick after the collision.
what is the angular momentum lcm of the system before the collision, with respect to the center of mass of the final system?
express lcm in terms of the given variables.

The angular momentum of the hockey stick and puck system before collision is .

The given parameters;
