The top in Figure P10.51 has a moment of inertia of i = kg ? m2 and is initially at rest so wi = . It is free to rotate about the stationary axis AA9. A string, wrapped around a peg along the axis of the top, is pulled in such a manner as to maintain a constant tension of f = N. If the string does not slip while it is unwound from the peg, what is the angular speed of the top after d = cm of string has been pulled off the peg?
