Answer:
The horsepower required is 235440 watt.
Step-by-step explanation:
To find : What horsepower is required to lift an 8,000 pound aircraft six feet in two minutes?
Solution :
The horsepower formula is given by,
![W=\frac{mgh}{t}](https://tex.z-dn.net/?f=W%3D%5Cfrac%7Bmgh%7D%7Bt%7D)
Where, W is the horsepower
m is the mass m=8000 pound
g is the gravitational constant g=9.81
t is the time t= 2 minutes
h is the height h=6 feet
Substitute all values in the formula,
![W=\frac{8000\times 9.81\times 6}{2}](https://tex.z-dn.net/?f=W%3D%5Cfrac%7B8000%5Ctimes%209.81%5Ctimes%206%7D%7B2%7D)
![W=\frac{470880}{2}](https://tex.z-dn.net/?f=W%3D%5Cfrac%7B470880%7D%7B2%7D)
![W=235440](https://tex.z-dn.net/?f=W%3D235440)
Therefore, The horsepower required is 235440 watt.
