An object of mass 5 kg on the end of a rope is rotated in a horizontal circle of radius 4 m with a constant speed of 8 m/s. What is the tension in the rope?

An object of mass 0.6 kg is whirled round in a vertical circle of radius 0.8 m on the end of a rope. What is the maximum and minimum tension in the rope when the mass rotates at 200 rev/min?
