A 19 m length of hose is wound around a reel, which is initially at rest. The inertia of the reel is 0.44 kgm2, and its radius is 0.18 m. When the reel is turning, friction at the axle exerts a torque of magnitude of 3.4 Nm on the reel. If the hose is pulled so the tension in it remains constant 29 N, how long does it take to completely unwind the hose from the reel
