Calculate the pressure exerted on the ground by a 57 kg person standing on one foot.
Assume that the bottom of the person’s foot is 13 cm wide and 28 cm long.
The answer is 1.5 X 10^4 Pa, but I can't seem to figure out how to get there. Please show steps so I can try to understand. Thanks.

Hey Veronica,
This is the equation for pressure: P=F/A. (57*9.81)/(.13)(.28)=1.53e4 Pa. Hope this helps.

P=F/A,
1Pa=1N/m^2
P=(57kg * 9.81m/s^2)/ (.13m * .28m)
= 559.17 N / 0.0346 m^2
= 1.536 * 10^4 Pa
1Pa=1N/m^2
P=(57kg * 9.81m/s^2)/ (.13m * .28m)
= 559.17 N / 0.0346 m^2
= 1.536 * 10^4 Pa
