An air puck of mass m1 is tied to a string and allowed to revolve in a circle of radius R on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table, and counterweight of mass m2 is tied to it. The suspended object remains in equilibrium while the puck on the tabletop revolves.
Find the tension in the string,
Find the radical force acting on the puck, and
Find the speed of the puck?
