Academics

A 5.00-N salmon swims 20.0m upstream against a current thatprovides a resistance of 1.50N. This portion of the stream rises atan angle of 10.0 degrees with respect to the horizontal.

a.) Howmuch work is done by the salmon against the current?

b.) What isthe gain in PE by the salmon?

c.) What is the total work that mustbe done by the salmon?

d.) If the salmon takes 40.0s to swim the distance, what power doesit exert in doing so?
