Solve the all parts of given question:
Question: A tennis ball connected to a string is spun around in a vertical, circular path at a uniform speed. The ball has a mass m = 0.15 kg and moves at v = 4.83 m/s. The circular path has a radius of R = 0.93 m.
Part A: What is the magnitude of the tension in the string when the ball is at the bottom of the circle?
Part B: What is the magnitude of the tension in the string when the ball is at the side of the circle?
Part C: What is the magnitude of the tension in the string when the ball is at the top of the circle?
Part D: What is the minimum velocity so the string will not go slack as the ball moves around the circle?
I need help to determine the magnitude of the tension in the string.
