You’ve been given the challenge of balancing a uniform, rigid meter-stick with mass M = 110 g on a pivot. Stacked on the 0-cm end of the meter stick are n identical coins, each with mass m = 2.9 g, so that the center of mass of the coins is directly over the end of the meter stick. The pivot point will be measured from the 0-cm end of the meter stick. Determine the distance da in cm if there is na = 1 coin on the end of the meter stick, and the system is to remain in static equilibrium.
