The 45-kg roll of paper rests along the wall where the
coefficient of kinetic friction is μ = 0.2. A vertical force of
P 40 N is applied to the paper. Neglect the mass of
the unraveled paper and take the radius of gyration of the
spool about the axle O to be ko = 70 mm. (Figure 1)
Determine the magnitude of the angular velocity of the roll when t = 8 s starting from rest.
Express your answer in radians per second to three significant figures.
