    Answer:

    The correct answer to the physics problem in pressure given above would be 1.5 N.

     

    First, I converted the cm^2 to m^ 2 (31.4 cm^2 = .00314 m^2).

    Then I computed for the force (F= mg = (47.1kg)(9.8m/s^2) = 461.58 N)  

    Consequently, I used the equation of pressure (P = Force/Area).

    P = 461.58 N / .00314 m^2

    P = 1.47 or 1.5 N
