Homework Help: physics

Posted by Sami on Thursday, November 3, 2011 at 7:24pm.

Suppose you need to measure the mass of an object, but have only a 7-kg standard mass and a meter stick. Place a knife edge under the 50-cm mark of the meter stick. Then put the 7-kg standard mass at the 39.1-cm mark and place the object so as to balance the standard mass. If the system is balanced when the object is at the 85.9-cm mark, find the unknown mass.
