QUESTION 11 A mass rotates at the end of a string, in the horizontal plane. If the string makes an angle of 30 degrees with the horizontal, and the string is155 meters long, then the velocity of the mass is O 4.12 m/s O 1039 m/s O 7.878 m/s O 12.20 m/s O cannot solve without knowing the mass O NOTA QUESTION 12 In the previous problem, now imagine that the person changes how they swing the mass so that the mass is swinging faster. In that case: o the mass becomes more vertical and the tension increases o the mass becomes more horizontal and the tension increases o the mass becomes more vertical and the tension decreases o the mass becomes more horizontal and the tension decreases o the tension is unchanged.
