\[it's thedw: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

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

I can also use r x mv right
