Chinook salmon are able to move upstream faster by jumping outof the water periodically; this behavior is calledporpoising. Suppose a salmon swimming in still water jumpsout of the water with a speed of 6.26 m/s at an angle of30°, sails through the air adistance L before returning to the water, and then swims adistance L under water at a speed of 3.28 m/s before beginning another porpoisingmaneuver. Determine the average speed of the fish.
