Conical problem need help finding tensions and periods

  1. Oct 5, 2007 #1
    A "conical pendulum", in which the bob (the small object at the lower end of the cord) moves in a horizontal circle at constant speed. (The cord sweeps out a cone as the bob rotates.) The bob has a mass of 0.060 kg, the string has length L = 0.90 m and negligible mass, and the bob follows a circular path of circumference 0.94 m.
    Find the Tension (in N) and Period (in s)

    Any help is appreciated thanx

    What is the component, parallel to the string, of gravitational acceleration acting on the mass? What is the component, parallel to the string, of centripetal acceleration acting on the mass?

    What is the kinetic energy of the rotating bob? What is its gravitational potential energy? What angular velocity corresponds to both?
