Mass is suspended and swung around, find angle?

  1. Sep 30, 2008 #1
    A mass m = 3.5 kg is suspended from a string of length L = 1.47 m. It revolves in a horizontal circle. The tangential speed of the mass is 3.44 m/s. What is the angle theta between the string and the vertical (in degrees)?

    Hey man. i just quickly did some trig and used Fc=mv(squared)/r. and got theta= roughly 35 to the vert. do u have answers with u?
