A mass of 1.6 kg is at the end of a rope to form yo-yo. Instead of being swung in a vertical circle, but instead of a horizontal circle it swings such that the circle it makes is parallel to the ground. When the mass is swinging at 13 m/s, it makes a circle of radius 1.5 meters. What is the tension in the rope in Newtons?
Homework Answers
If the mass describes a circumference who's plane is parallel to the ground, the tension T in the rope must be such to counter the weight of the yo-yo and at the same time provide the centripetal force Fc on the radial direction, to keep the circular motion going:

A ball of mass 4.4 kg is attached to a pole by two ropes: a horizontal rope under tension T1, and a rope under tension T2 which makes an angle 0 = 44.6 degrees with the vertical as shown in the diagram. The ball moves in a horizontal circle of radius L = 1.9 at constant speed of V| = 19.2 m What is the tension T? Answer in Newtons (N).
