Calculate the pressure exerted on the ground by a79kg person standing on one foot. Assume that the bottom of the person's foot is 13cm wide and 28cm long.

  • physicS -

    Assume the footprint is a rectangle and divide the weight (Mg) by the area of that rectangle.

  • physic -

    2.13

  • physic -

    First convert the lengths from cm to m.
    After that, you multiply them to find the area, and divide the weight by the area.
    A=(0.13)(0.28)=0.0364
    P=(75)/(0.0364)=2100 rounded
    in scientific notation that equals
    2.1*10^3 Pa
