Question

A Chinook salmon can jump out of water with a speed of 6.60 m/s . How far horizontally ? can a Chinook salmon travel through the air if it leaves the water with an initial angle of ?=26.0° with respect to the horizontal? (Let the horizontal direction the fish travels be in the +? direction, and let the upward vertical direction be the +? direction. Neglect any effects due to air resistance.) Please clearly mark the solution. Please take a clear picture (if taking a photo). Please write legibly (if handwriting)

Answer #1

Chinook salmon are able to move upstream faster by jumping out
of the water periodically; this behavior is called porpoising.
Suppose a salmon swimming in still water jumps out of the water
with a speed of 6.26 m/s at an angle of 40°, sails through the air
a distance L before returning to the water, and then swims a
distance L under water at a speed of 3.54 m/s before beginning
another porpoising maneuver. Determine the average speed of the...

of 10.0 m/s at an angle of 45º above the horizontal. What is the
horizontal distance of the point where he lands from the point
where the leaves the ground?
Select one:
a. 4.8 m
b. 3.4 m
c. 10.2 m
d. 5.1 m
