Centripetal force question

  1. Oct 7, 2006 #1
    an athlete swings a 6.18kg ball horizontally on the end of a rope. The ball moves in a circle of radius 1.03m at an angular speed of 0.736 rev/s.
    what is the tangential speed of the ball? Answer in units of m/s

    WHAT is angular speed? and how would you solve t his?

    thanx so much

    Well, what do you think angular speed is? What is the relation between the angular speed and the radius of the circle?
