Question: i need someone to explain c and d to me...

Question details

5. A flow is described by velocity field V ati +bj, where a 0.4 m/s2 and b 2 m/s. a) At t - 2 s, what are the coordinates of the particle that passed through point (2 m, 1m) att- 0 s? b) At t 3 s, what are the coordinates of the particle that passed through point (2 m, 1 m) at t 2s? c) Plot the pathlines through point (2 m, 1 m) for 1 y s 15m. d) Plot the streaklines at t 3 s andt6 s through point (2 m, 1 m) for 1s y s 15 m. (Hint: Two different particles are released from the same point at different release times. You should plot pathlines for each particle. When plotting, the horizontal axis should be x- axis and the vertical axis should be y-axis.)I need someone to explain C and D to me.

I know the answers are on Zookal but I dont really understand what they're looking for.

If you can't explain just make sure the work is legible.
