A cylindrical fishing reel has a mass of 0.85 kg and a radius of 4.5 cm. A friction clutch in the reel exerts a restraining torque of 1.6 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 66 rad/s2.
a) Find the force of the fish on the line.
b) Find the amount of line that unwinds in .5 seconds.
I = .5mr^2
theta = .5at^2
The Attempt at a Solution
I found the moment of inertia to be 8.606. What I don't understand is how to relate the torque to the moment of inertia. I dont know if my calculator should be set to radians or degrees, but I tried both ways and got them both wrong.
