in 1994, Mata Jagdamba of India had very long hair. It was 4.23m long. Suppose Mata conducted experiments with her hair. First, she determined that one hair strand could support a mass of 25g. She then attached a smaller man to the same hair strand and swung it in the horizontal plane. If the strand broke when the tangential speed of the mass reached 8.1 m/s, how large was the mass?
