Answer:
0.447 sec
Explanation:
velocity = distance/ time
distance 'h' is a function of time 't' given by
⇒ differentiating equation
⇒ velocity = 
⇒ acceleration = 
= 24 
deceleration due to gravity = -9.8 m/
= - 9.8 x 3.281 = - 32.154 ft/
Net deceleration = 24 - 32.154 = - 8.15 ft/
at maximum height v = 0
= 
+ 2ah
⇒ 0 = 
+ 2 (-8.15)h
⇒ h = 118.72 ft⇒
118.72 = 12
+ 44t + 16
⇒ 
- 102.72 = 0
⇒ t = -44 ± 
/ (2 x 12)
t = 0.447 sec
Although America fought in many wars since, World War 2 was the last time the nation declared war (actually against two nations at the time). One declaration of war with Japan, and one declaration of war with Germany. I hope this helped !!

Some of the Environmental issues that are associated with Spray irrigation are:
1. Spread of water born diseases
2. Pollution of waters
3. Sensitivity to the wind, causing evaporation losses
4. Increased chance of waterlogging area formation
Some of the facts associated with Spray irrigation are :
1. It can be either a high-pressure system or a low-pressure system sprinkler. (mostly modern version)
2. It can adapt to the farm slope or terrain.
3. There is a rotor type version and an impact spray version
