An air puck of mass 0.031 kg is tied to a string and allowed to revolve in a circle of radius 1.5m on a frictionless horizontal surface. The other end of the string passes through a hole in the center of the surface, and a mass of1.4 kg is tied to it, as shown. The suspended mass remains in equilibrium while the puck revolves on the surface. What is the magnitude of the force that maintains circular motion acting on the puck? 0.031 kg 1.5 m 1.4 kg Your answer
