A 17.0-m length of hose is wound around a reel, which is originally at rest. The moment of inertia of the reel is 0.490kg·m2, and its radius is 0.160 m. When turning, friction at the axle exerts a torque of magnitude 3.20 N·mon the reel. If the hose is pulled so that the tension in it remains a constant 25.0 N, how long does it take to totally unwind the hose from the reel? Neglect the mass of the hose, and suppose that the hose unwinds without slipping.
