A mass is tied to a string and made to rotate in a horizontal plane while other end of string is held vertically by a man. The radius of the string on the table is changed from 0.29 to 0.11 as the dstring is pulled. The initial velocity of mass is 1.2 m/s. Find:

1) Final speed

2) Tension in string

3) Work done.
