The acceleration of high-speed aircraft is sometimes expressed in g's (in multiples of the standard acceleration of gravity). Determine the upward force, in N, that a 78.03-kg person would experience in an aircraft whose acceleration is 5.05 g's. Assume the standard acceleration of gravity is 8.23 m/s^2.

    3888.23 N

    Explanation:

    m = mass of the person = 78.03 kg

    g = standard acceleration due to gravity = 8.23 m/s²

    a = acceleration of the aircraft = 5.05 g = 5.05 x 8.23 = 41.6 m/s²

    F = upward force the person experience

    Force equation for the motion of person is given as

    F - mg = ma

    Inserting the values

    F - (78.03) (8.23) = (78.03) (41.6)

    F = 3888.23 N
