An athlete swings a 3.60 kilogram ball horizontally on the end of a rope. The ball moves in a circle of radius 0.960 meter at an angular speed of 0.670 rev/s.
(a) Estimate what is the tangential speed of the ball?
m/s
(b) Estimate what is its centripetal acceleration?
m/s2
(c) If the maximum tension the rope can withstand before breaking is 104 Newton, estimate what is the maximum tangential speed the ball can have?
