on the end of a rope. The ball moves in a
circle of radius 0.55 m at an angular speed of
0.35 rev/s.
What is the tangential speed of the ball?

  1. 0.35 rev/s means that w = 2.20 rad/s
    is the so-called angular velocity

    Multiply w by the radius for the tangential speed.

  2. if the tangential speed of a ball is 1.2874 . what is the centripetal force ?

    If the maximum tension the rope can withstand before breaking is 159.9 N, what is the
    maximum tangential speed the ball can have?
    Answer in units of m/s
