Chinook salmon are able to move through water especially fast 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 velocity 6.65 m/s at 48.1â° above the horizontal, sails through the air a distance l before returning to the water, and then swims the same distance l underwater in a straight, horizontal line with velocity 3.79 m/s before jumping out again. (a) determine the average velocity of the fish for the entire process of jumping and swimming underwater. incorrect: your answer is incorrect. your response differs from the correct answer by more than 10%. double check your calculations. m/s (b) consider the time interval required to travel the entire distance of 2l. by what percentage is this time interval reduced by the jumping/swimming process compared with simply swimming underwater at 3.79 m/s?
