An air puck of mass 0.27 kg is tied to a string and allowed to revolve in a circle of radius 1.0 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 1.4 kg is tied to it. The suspended mass remains in equilibrium while the puck on the tabletop revolves. (a) What is the tension in the string?1 N (b) What is the force causing the centripetal acceleration on the puck?2 N (c) What is the speed of the puck?3 m/s
