Question
An air puck of mass m, = 0.17 kg is tied to a string and allowed to revolve in a circle of radius R = 1.2 m on a frictionless horizontal table. The other end of the
string passes through a hole in the center of the table, and a mass of
m2
= 1.3 kg is tied to it (see the figure below). The suspended mass remains in equilibrium
while the puck on the tabletop revolves.
