Show complete solution A deep-sea fisherman hooks a big fish that swims away from the boat, pulling the fishing line from his fishing reel. The whole system is initially at rest, and the fishing line unwinds from the reel at a radius of 4.50 cm from its axis of rotation. The reel is given an angular acceleration of 110 rad/s2 for 2.00 s. Now the fisherman applies a brake to the spinning reel, achieving an angular acceleration of − 300 rad/s2. Determine the time for the reel to come to a stop.
