1. Derive the streamline y(x) that goes through point (0, 0) at time t = 0 (the final expression for y should be a function of x only). Sketch the result.
2. Derive the pathline y(x) of the fluid particle that goes through point (0, 0) at t = 0 (the final expression for y should be a function of x only). Sketch the result.
3. Calculate the acceleration vector. Your answer should indicate clearly the magnitude and direction.
