Rotational N2L

  1. Nov 20, 2014 #1
    1. The problem statement, all variables and given/known data

    A cylindrical fishing reel has a mass of
    0.623 kg and a radius of 1.83 cm. A fric-
    tion clutch in the reel exerts a restraining
    torque of 0.614 N · m if a fish pulls on the line.
    The fisherman gets a bite, and the reel be-
    gins to spin with an angular acceleration of
    49.1 rad/s2.
    What force does the fish exert on the line?
    Answer in units of N

    2. Relevant equations
    Torque=I(alpha)
    I=1/2mr^2
    (torque)=rfsin(theta)
    3. The attempt at a solution
    Is it as easy (torque)=rF?

    You are required to show something here. A free body diagram would be good, plus any thoughts, a description of what you have tried (with working) or an explanation of why you cannot get started.
