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 6.36 m/s at an angle of 45°, sails through the air a distance of l underwater at a speed of 3.58 m/s before beginning another porpoising maneuver. determine the average speed of the fish.
