A ball of mass m1 = 4.00 kg is tied to another ball of mass m2 = 3.00 kg by a string of length 0.500 m. The two balls are swung in a vertical circle by a second string of length 0.500 m connected to m2. As the balls rotate, the strings remain parallel. At the top if the circle, m2 is moving at 4.00 m/s. (a) Draw a free-body diagram for each mass at this instant. (3 marks) (b) What is the tension in the string connecting the two balls at this instant? (4 marks) (c) What is the tension in the string connecting m2 to the centre of the circle at this instant? (3 marks)
