As a fish jumps vertically out of the water, assume that only two significant forces act on it: an upward force exerted by the tail fin and the downward force due to gravity. a record chinook salmon has a length of m and a mass of kg. if this fish is moving upward at m/s as its head first breaks the surface and has an upward speed of m/s after two-thirds of its length has left the surface, assume constant acceleration and determine (a) the salmon’s acceleration and (b) the magnitude of the force f during this interval.
