Hint: Find the work done by the force acting on the string (you know the F and d) and set that equal to the KE of rotation for the top. A top has a moment of inertia of 3.13 ×10-4kg · m2 and is initially at rest. It is free to rotate about a vertical stationary axis. A string around a peg along the axis of the top is pulled, maintaining a constant tension of 3.70 N in the string. If the string does not slip while it is wound around the peg, what is the angular speed of the top after 58.1 cm of string has been pulled off the peg? Answer in units of rad/s.
