(Figure 1)A hockey stick of mass m, 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 vo 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.

Hockey Stick and Puck
(Figure 1)A hockey stick of mass ms and length I 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 voin 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.
