What horsepower is required to lift an 8,000 pound aircraft six feet in two minutes?

Dafna11 [192]

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,

$W=\frac{mgh}{t}$

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,

$W=\frac{8000\times 9.81\times 6}{2}$

$W=\frac{470880}{2}$

$W=235440$

Therefore, The horsepower required is 235440 watt.
