A cylindrical ﬁshing reel has a mass of
0.899 kg and a radius of 5.21 cm. A friction clutch in the reel exerts a restraining torque of 1.43 N · m if a ﬁsh pulls on the line.
The ﬁsherman gets a bite, and the reel begins to spin with an angular acceleration of
What force does the ﬁsh exert on the line?
