Asked by Frankie
A local ice hockey team has asked you to design an apparatus for measuring the speed of the hockey puck after a slap shot. Your design is a 2.00-m-long, uniform rod pivoted about one end so that it is free to rotate horizontally on the ice without friction. The 1.70-kg rod has a light basket at the other end to catch the 0.163-kg puck. The puck slides across the ice with velocity v (perpendicular to the rod), hits the basket, and is caught. After the collision, the rod rotates.If the rod makes one revolution every 0.736 s after the puck is caught, what was the puck’'s speed just before it hit the rod?
Right now I am trying to relate angular momentum to linear momentum because I think it is conserved and I keep getting 60 m/s but that isn't right.
