An object of mass m, is tied to a string and allowed to revolve in a circle of radius r= 19,7 mon 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 as shown in figure below. The suspended mass remains in equilibrium while the puck on the tabletop revolves. If the period of the puck is T = 9,7 s, find the value of m, in units of kg. Take g=9.8 m/s2, and round off your result to 2 decimal places. r m₂ m₁
