005 (part 1 of 2) 10.0 points An air puck of mass 0.030 kg is tied to a string and allowed to revolve in a circle of radius 1.4 m on a frictionless horizontal surface. The other end of the string passes through a hole in the center of the surface, and a mass of 1.3 kg is tied to it, as shown. The suspended mass remains in equilibrium while the puck revolves on the surface. 1.4 m 1.3 kg 0.03 kg What is the magnitude of the force that maintains circular motion acting on the puck? The acceleration due to gravity is 9.81 m/s 2 . Answer in units of N. 006 (part 2 of 2) 10.0 points What is the linear speed of the puck? Answer in units of m/s.
