What pressure did the astronaut exert on the lunar soil, standing still, whose mass with equipment was 175 kg, and the boot left a trail with an area of 410 cm2? Free fall acceleration on the Moon is 1.62 m / s2.
p = F: S
F = 410 cm2 * 2 = 820 cm2
P = mg
m = 175 kg
g = 1.62 m / s2
175 * 1.62 = 283.5 N
283.5: 820 = 0.34573170731 approx.0.4 Pa
answer: approximately 0.4 Pa
