The air pressure on Mars is about 1% that of Earth's at sea level. But wind speeds on Mars can be higher, up to maybe 60 mph sustained (actually I have come across several different figures, some going very high indeed.)
So if you hold your hand out in a 60 mph wind that is 1% the density of air, can you feel it? Would you feel the pressure against your back? Could it blow you over? Could it blow a landing vehicle over, as in Weir's book, The Martian? Thank you!
(edit) This question appears to be the same as the other question (asking what it would "feel like to be in a Martian dust storm"), but in the full post it is clear that question is really whether or not the sand in Martian windstorms would be abrasive. I am asking, literally and exactly, whether or not you could feel the wind as pressure on your body; my question has nothing to do with sand. The wind speed is often higher than on Earth, but the atmospheric density is far lower, making this a worthy question, I feel.
