A puck on a horizontal, frictionless surface is attached to a string that wraps around a pole of finite radius, as shown in the figure .
As the puck moves along the spiral path, does its speed increase, decrease, or stay the same?

angular momentum remains constant because no torque.
Therefore speed increases and radius decreases.
Therefore speed increases and radius decreases.
