volume_muteA 200-lb man mentioned about weighs about 800 N, and one show's dimensions are about 8 cm by 25 cm.
Calculate the pressure a man exerts on the floor (in N/cm2) when he stands on one foot.
Correct Answer
4 N/cm2
Explanation
the pressure in newton would be
$\text{Pressure} = \frac{\text{Man's weight in Newton}}{\text{area of one shoe in cm}}$
$\text{Pressure} = \frac{800 \text{ N}}{8 \text{ cm} \cdot 25 \text{ cm}} = 4 \text{ N/cm}^2$
