A flow in the x – y plane is given by the following velocity field:

u=5 and v=10m m/s 0<t<20s

and u=-5 and v=0 m/s 20<t<40s

Paint is released at the starting point. (x,y,t)=(0,0,0)

(A) For two particles released from one at t=0 s and the other at t=20 s, road lines at t = 30 draw for.

(B) Draw flow lines at t=10 s and t=30 s on the same graph.
