Question

use the formula f = pa to help jenna solve for the force, f, of the air exerted on the aircraft door if the given pressure, p, is 11.8 psi (pounds per square inch) and the area, a, of the door is 2,160 in²

Explanation:

Step1: Substitute values into formula

Given \(F = PA\), \(P = 11.8\) psi, \(A=2160\space in^{2}\).
Substitute into formula: \(F=(11.8)(2160)\)

Step2: Calculate the product

\(F = 11.8\times2160=25488\)

Answer:

\(F = 25,488\) pounds
