A cylindrical fishing reel has a moment of inertia of i 60, Ask an Expert

Academics

A cylindrical fishing reel has a moment of inertia of I = 6.0 10-4 kg·m2 and a radius of 4.0 cm. A friction clutch in the reel exerts a restraining torque of 1.3 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 70 rad/s2.

(a) What is the force of the fish on the line?

(b) How much line unwinds in 0.50 s?
