Part A
The reel of cable has a mass of 360 \kg and a radius of gyration of
kд = 0.75 m. The force P = (20t² + 80) N, where t is in seconds.
Neglect the mass of the unwound cable, and assume it is always at a
radius of 0.5 m. (Figure 1)
Determine the magnitude of the angular velocity of the reel when t = 2 s, starting from rest.
Express your answer in radians per second to three significant figures.
