A puck (mass m1 = 1.30 kg) slides on a frictionless table as shown in the figure below. The puck is tied to a string that runs through a hole in the table and is attached to a mass m2 = 3.9 kg. The mass m2 is initially at a height of h = 3.9 m above the floor with the puck traveling in a circle of radius r = 1.04 m with a speed of 3.9 m/s. The force of gravity then causes mass m2 to move downward a distance 0.39 m.

What is the new speed of the puck? m/s
