P3.50 from textbook) A chinook salmon, which is a type of fish, has a maximum underwater speed of 3.58, but it can jump out of water with a speed of 6.26. To move upstream past a waterfall the salmon does not need to jump to the top of the fall, but only to a point in the fall where the water speed is less than 3.58, it can then swim up the fall for the remaining distance. Because the salon must make forward progress in the water, let's assume it can swim to the top if the water speed is 3.00 or less. Assume the water has a horizontal speed of 1.50 as it passes over the top ledge of the waterfall.
