An air puck of mass 0.289 kg is tied to a string
and allowed to revolve in a circle of radius
0.51 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 0.98 kg
is tied to it. The suspended mass remains in
equilibrium while the puck revolves.
