The air puck of mass 0.028 kg is tied to the string and permitted to revolve in a circle of radius 1.5 m on the frictionless horizontal surface. The other end of string passes via a hole in the center of the surface, and mass of 2.0 kg is tied to it. The hanged mass remains in equilibrium whereas the puck revolves on the surface. Acceleration of gravity is around 9.81 m/s^2.

i) Determine the magnitude of the force which maintains circular motion acting on the puck?

ii) Determine the linear speed of the puck? Answer must be in units of m/s.
