As a fish jumps vertically out of the water, suppose that just two significant forces act on it: an upward force F applied by the tail fin and the downward force due to gravity. A record Chinook salmon consists of a length of 1.50 m and a mass of 54.5 kg. When this fish is moving upward at 3.00 m/s as its head first breaks the surface and consists of an upward speed of 7.30 m/s after two-thirds of its length has left the surface, suppose constant acceleration and find out the given.
(i) The salmon's acceleration?
