Question

How much horsepower would theoretically be necessary to allow an 8400 pound airplane climb from sea level to 10,000 feet MSL in 10 minutes?

A) 255 horse power
B)140,000 horsepower
C) power can not be determined without velocity

Answer 1

To calculate the required horsepower for an airplane to climb from sea level to 10,000 feet in 10 minutes, calculate the work done and power required using relevant formulas.

Step-by-step explanation:

To calculate the amount of horsepower necessary for an airplane to climb from sea level to 10,000 feet in 10 minutes, we need to consider the work done and the power required.

1. First, we calculate the work done by the airplane using the formula: Work = Force x Distance. The force can be calculated using the weight of the airplane and the acceleration due to gravity.
2. Next, we calculate the power required using the formula: Power = Work / Time. We convert the power to horsepower by dividing by 745.7.
3. Afterwards, we plug in the values into the formulas and calculate the result.

The correct answer is A) 255 horsepower.
