Extracted text: Suppose the wheel (R = 20.0 cm, M = 2.60 kg) is rotated at a constant rate so that the mass m = 0.610 kg has an upward speed of 3.65 m/s when it reaches a point P. At that moment, the wheel is released to rotate on its own. It starts slowing down and eventually reverses its direction due to the downward tension of the cord. What is the maximum height, h, the mass will rise above the point P?
