A string wrapped around a peg (diameter=2.00 cm) along the axis of a top is pulled with a constant tension of 5.92 N. Starting from rest, the top reaches an angular velocity of 480 rpms after turning 5 complete revolutions (at this point, the string is completely unwound). what is the moment of inertia of the top?
