The 100-kg spool is resting on the inclined surface for which the coefficient of kinetic friction is μk = 0.11. The radius of gyration about the mass center is kG = 0.26 m

Determine the angular velocity of the spool, measured clockwise, when t = 7 s after it is released from rest.

The 100-kg spool is resting on the inclined surface for
which the coefficient of kinetic friction is μ = 0.11. The
radius of gyration about the mass center is
kg = 0.26 m. (Figure 1)

Determine the angular velocity of the spool, measured clockwise, when t = 7 s
after it is released from rest.
Express your answer in radians per second to three significant figures.
Enter positive value if the angular velocity is clockwise and negative value
if the angular velocity is counterclockwise.
