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/s?for 2.00 s. a. What is the final angular velocity of the reel after 2 s? b. How many revolutions does the reel make? c. Now, the fisherman applies a brake to the spinning reel, achieving an angular deceleration of -300 rad/s2. How long will it take until it stop?
