An air puck of mass 0.331 kg is tied to a string and allowed to revolve in a circle of radius 0.82 m on a horizontal, frictionless table. The other end of the string passes through a hole in the center of the table and a mass of 1.58 kg is tied to it. The suspended mass remains in equilibrium while the puck revolves around it. The acceleration of gravity is 9.8 m/s2.
