Solve the all parts of given question:

Question: As a fish jumps vertically out of the water, assume that only two significant forces act on it: an upward force F exerted by the tail fin and the downward force due to gravity. A record Chinook salmon has a length of 1.50 m and a mass of 47.5 kg. If this fish is moving upward at 3.00 m/s as its head first breaks the surface and has an upward speed of 4.80 m/s after two-thirds of its length has left the surface, assume constant acceleration and determine the following.

Part A: What is the salmon acceleration?

Part B: What is the magnitude of the force F during this interval?

Please show all intermediate steps and formulas.
