    well torque is easy

    \[it's the|dw:1359765105446:dw| we know the lever arm however we need to make the force perpendicular to the arm i think if i remember right

    we need to find the perp force of that force on it which is a component of that force

    so if you look t's the sin of that angle

    so now you have \[\tau=fRsin(\theta)=2*3*sin(30)\]

    you're given velocity so you can find angular velocity

    now you need to find the moment of inertia for hte object... you can perhaps find this using torque equation

    \[\tau=fR=I\alpha\]

    you need to find hte moment of inertia of this object somehow

    I can also use r x mv right
