1. The problem statement, all variables and given/known data

A cylindrical fishing reel has a mass of 0.65 kg and a radius of 4.3 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 66 rad/s2.

(a) Find the force of the fish on the line.

______N

(b) Find the amount of line that unwinds in 0.50 s.

______m

3. The attempt at a solution

for the fishing reel, I=m*r^2

Net torque equals I*α

α=66 rad/s^2

I will assume that the torque from the line is at the edge of the radius:

F*4.3/100-1.3=I*66

where F is the force of the fish

F=32.1 N

θ=.5*α*t^2

θ=.5*66*.5^2

8.25 radians

d=2*π*r*θ

=2*3.14*4.3*8.25/100

2.23 m

but it says those answers are wrong. what do i do?
