A small object of mass \(0.50 \text{ kg}\) travels in the \(xy\)-plane with a constant velocity \(\vec{v} = (6.0 \text{ m/s})\hat{i}\) along the line \(y = 4.0 \text{ m}\). What is the magnitude of the angular momentum of the object relative to the origin \((0,0)\) at the instant the object passes through the point \((3.0 \text{ m}, 4.0 \text{ m})\)?
