A model aircraft of mass 250 g is flying with a constant velocity vector of v=(24i−7j) m/s\mathbf{v} = (24\mathbf{i} - 7\mathbf{j})\text{ m/s}v=(24i−7j) m/s, where i\mathbf{i}i and j\mathbf{j}j are perpendicular horizontal unit vectors.
Calculate the magnitude of the momentum of the model aircraft.
