an air puck of mass m1= 0.25 kg is tied to a string and allowed to revolve in a circle of radius R=1.0m on a frictionless horizontal table . the other end of the string passes through a hole in the center of a table and a mass of m2=1.0kg is tied to it. the suspended mass remains in equilibrium while the puck on the tabeltop revolves.
a) what is the tension in the string
b) what is the horizontal force acting on the puck
c) what is the speed of the puck

    the tension on the string has to be equal to the weight hanging down.

    force on the puck equals tension.

    force=m v^2/r solve for v
