A flat puck with mass M=.10kg is rotated in a circle with radius R=.20 m on a frictionless air-hockey tabletop at constant speed. It is helf in this orbit by a light cord connected to a dangling blck with mass m through a central hole. If the puck is observed to complete 5.0 whole revolutions per socond, then what is the weight G=mg of the dangling block?
