E(v)= (aLv^3)/(v-u)

Where E is measured in foot-pounds and a is a constant.

a) Evaluate the limit of E(v) as v-->u+ and interpret your result

b) Evaluate the limit of E(v) as v-->infinity and interpret your result

**drwls**, Saturday, February 6, 2010 at 11:38pma) as v -> u the Energy required becomes infinite because the fish does not move and requires infinite time to go a distance L.

b) as v--> infinity, the energy required is proportional to v^2 (which is true for the fluid drag force), as the stream velocity becomes negligible compared to v.

Energy = force x distance.
