2.10 Consider the velocity field V =axi+by 1+ct j, where a=b=2 s−1 and c=0 4 s−1. Coordinates are measured in meters.

For the particle that passes through the point x,y = 1,1 at the instant t =0, plot the pathline during the interval from t =0 to 1.5 s. Compare this pathline with the streamlines plotted through the same point at the instants t =0, 1, and 1.5 s.
