String is wrapped around an object of mass 1.2 kg and moment of inertia 0.06 kg m2. With your hand you pull the string

straight up with some constant force F such that the center of the object does not move up or down, but the object spins

faster and faster (Figure 11.111). This is like a yo-yo; nothing but the vertical string touches the object. When your hand is

a height y0 = 0.25 m above the floor, the object has an angular speed ω0 = 12 radians/s. When your hand has risen to a

height y = 0.66 m above the floor, what is the angular speed ω of the object? Your answer must be numeric and not contain

the symbol F
