Consider a velocity field V = axiˆ + by(1+ ct) ˆj , where a=b=2 sec-1, and c=0.4sec-1. 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 sec. Compare this pathline with the streamline through the same point at the instant t=0.
