The velocity v and maximum height h of the water being pumped into the air are related by the equation v=\sqrt(2gh) where g is the acceleration due to gravity (32 feet/second^2). a. determine the equation that will give the maximum height of the water as a function of its velocity b. the mayfield fire department must purchase a pump that is powerful enough to propel water 80 feet in the air. will a pump that is advertised to project water with a velocity of 75 feet/second meet the fire department’s needs? explain.

The velocity v and maximum height h of the water being pumped into the air are related by the equation

v=

where g = 32

(a) To find the equation that will give the maximum height of the water , solve the equation for h

v=

Take square root on both sides

= 2gh

Divide by 2g on both sides

= h

So maximum height of the water h =

(b) Maximum height h= 80

velocity v= 75 ft/sec

Given g = 32

h =

h =

h= 87.89 ft

The pump withe the velocity of 75 ft/sec reaches the maximum height of 87.89 feet. 87.86 is greater than the maximum height 80 feet.

So the pump will meet the fire department needs.

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
