A flow in the $x-y$ plane is given by the following field:

$u=3$ and $v=6m$ s for $v=0ms(x=y=0)t=0t=30st=0t=20st=10st=30s20.$

Dye $is$ released $at$ the origin $(x=y=0)$ for $t=0.$

$(a)$ Draw the pathline $att=30s$ for two particles that were released from the origin $-$ one

released $att=0$ and the other released $att=20s.$

$(b)On$ the same graph draw the streamlines $at$ times $t=10s$ and $t=30s\mathrm{.}0$ and $v=0ms$ for $20.$

Dye $is$ released $at$ the origin $(x=y=0)$ for $t=0.$

$(a)$ Draw the pathline $att=30s$ for two particles that were released from the origin $-$ one

released $att=0$ and the other released $att=20s.$

$(b)On$ the same graph draw the streamlines $at$ times $t=10s$ and $t=30s.$
