Use g=10m/s/s
A 500 gram meter stick has a center of mass at the 50 cm mark. You place a pivot at the 60 cm mark and hang 100 grams at the 70 cm mark. How much mass must you hang at the 90 cm mark to balance the system?
A nonuniform, 80.0-g, meterstick balances when the support is placed at the 51.0-cm mark. At what location on the meterstick should a 5.00-g tack be placed so that the stick will balance at the 50.0 cm mark?
In order to balance a meterstick at the 27 cm mark, how much weight would you need to hang at the 10 cm mark? Assume the stick weighs 200 g and its center of mass is at 50 cm.
