Question1

As a fish jumps vertically out of water, suppose that only two significant forces act on it: an upward force F exerted by the tail fin and downward force due to gravity. A record Chinook salmon has a length of 1.50 m and a mass of 61.0 kg. If this fish is moving upward at 3.00 m/s as its head first breaks surface and has an upward speed of 6.00 m/s after two-thirds of its length has left the surface, assume constant acceleration and determine

(a) Salmon's acceleration and

(b) magnitude of the force F during this interval.
