Problem 2: A ball of mass m = 2.0 kg is connected to 2 ropes. The two ropes are connected to a pol that is rotating at a constant angular speed w. The two ropes have an equal tension T. The rope on th bottom makes an angle of 60° with the pole and and the rope on the top makes an angle of 60° with th horizontal. The ball is going around in a circle at a constant speed v and a radius r = 0.87 m (unifor circular motion). (a) What is v, the speed of the ball? (b) What is T, the tension on each of the ropes? 60° 60 m 3
