A physics student whirls a rubber stopper around in a horizontal circle. Suddenly the string breaks. What is the speed of the rubber stopper the moment the string breaks if the radius of the circle is 0.75 m, the mass of the stopper is 45 grams, the angle θ in the diagram is 30 degrees, and the counter weight is 100 grams? Use g = 10 m/s^2.
