If the archerfish spits its water 30 degrees from the horizontal aiming at an insect 1.2 m above the surface of the water, how fast must the fish spit the water to hit its target? The insect is at the highest point of the trajectory of the spit water. Use g = 10 m/s2.

The speed is  

Explanation:

From the question w are told that

    The angle  made is

     The distance  above the surface of the water is  

     The  value of  

The maximum height attained by the fish is mathematically evaluate as

Making v which is the speed of the fish the subject of the formula

  substituting values

a is the best answer your welcome
