What is the fastest speed at which a human has ever traveled on ski?

Answer 1

The fastest Traveling Human To answer this question, it needs to be clarified a bit first. Since all motion (and therefore speed) must be measured relative to something, we need to establish what we are measuring the speed of the fastest human WITH RESPECT TO.

It seems natural to assume that we are interested in how fast one person has ever gone past another. Or, equivalently, how much FASTER one person has gone than another. Since we are all hurtling through space at enormous speed, the humans that have gone FASTER than others, would be those discussed in the Apollo answer.

This has got to be some of the Apollo astronauts.

On re-entry of their command module to the Earth's atmosphere at the end of their mission they had been falling from the height of the moon's orbit. IIRC, Apollo 10 was the fastest re-entry of all the Apollo missions.

As it hit the top of the earth's atmosphere and started slowing down, Apollo 10's command module, with astronauts Thomas Stafford, John Young, and Eugene Cernan inside, was traveling at about 11.1 km/sec, which works out to 6.9 miles/sec, or 24,840 miles per hour.

Strange as it may seem and a bit boring, as Apollo 10 sounds very fast. The actual answer is that the whole human race are traveling much faster than that.

We are all part of:-

The Earth rotating around its axis at approximately 1,674.4 km/h - 1,040.4 mph.

The Earth revolving around the Sun at approximately 107,218 km/h - 66,622 mph.

The Earth and the Sun is traveling around the galactic core at around 828,000 km/h - 514,495 mph.

However, the record must be our Galaxy though. It is moving at 1,987,200 km/h - 1,234,789 mph through space.

One last thought. We could add all these answers together if we were on the outer edge of each orbit at the same time. So it could be 2,924,092 km/h - 1,816,946 mph.

Therefore, we are all going very fast already at 812.2 km/sec - 504.7 miles/sec or 0.27% of the speed of light or Mach 2,387 (Mach = spped of sound)

I still like the Apollo answer and perhaps we could even add their speed to that of us all on Planet Earth to make the ultimate record :-)

Answer 2

For regular downhill skiing the average is about 15-20 mph

Olympic ski racing averages 40-50 mph

and

The fastest recorded speed is 156 mph
