Homework Statement
Please help. Have no clue?
A hockey stick of mass m_s and length L is at rest on the ice (which is assumed to be frictionless). A puck with mass m_p hits the stick a distance D from the middle of the stick. Before the collision, the puck was moving with speed v_0 (note: a v with subscript zero) 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.
Homework Equations
i suppose v_f=v_0+m_p/m_s+m_p
but it gives a wrong answer.
As for the others, i have no clue. please help..
