A flow is described by velocity field \(\vec{V}=a \hat{i}+b x \hat{j}\), where \(a=2 \mathrm{~m} / \mathrm{s}\) and \(b=1 \mathrm{~s}^{-1}\). Coordinates are measured in meters. Obtain the equation for the streamline passing through point \((2,5)\). At \(t=2 \mathrm{~s}\), what are the coordinates of the particle that passed through point \((0,4)\) at \(t=0\) ? At \(t=3 \mathrm{~s}\), what are the coordinates of the particle that passed through point \((1,4.25) 2 \mathrm{~s}\) earlier? What conclusions can you draw about the pathline, streamline, and streakline for this flow?
