Answer:
28.1 m/s
Explanation:
= Initial velocity of the fish = 1.52 m/s
y = Height of the bird = 40 m
= Acceleration in y axis = 
= Initial velocity in y axis = 0


The final velocity in x direction will remain the same as the initial velocity as there is no acceleration in the x direction 
Resultant velocity is given by

The fish is moving at a velocity of 28.1 m/s when it hits the water.
270/70^2 = x/80^2
Cross multiply
270 (6400) = 4900x
x = 270(6400)/4900
352 and 32/49 feet
