A fish takes the bait and pulls on the line with a force of2.2N. The fishing reel, which rotates without friction, is acylinder of radius 0.055m and mass 0.99kg. Assume the reelhas a friction clutch that exerts a restraining torque of0.047N×m.
a) what is the angularacceleration of the fishing reel?b) How much line does thefish bull from the reel in 0.25s?
