**Damon**, Tuesday, June 22, 2010 at 12:53pmYou know the length of the meter stick, one meter (100 cm).

First we need to find the center of gravity. We know that is at 49.7 am because that is where it balances all by itself.

now we put the 50 g mass on,

take moments about the 39.2 balance point.

50 (39.2 - 10) = m (49.7-39.2)

solve for m
