An athlete swings a 3.46 kg ball horizontally
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?

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.

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
