<h3>Reducing Surface Area.</h3>
If the surface area becomes smaller, the pressure becomes larger.
Due to friction from sliding against the ground, the player decelerates in 1 direction. Thus his momentum decreases.
The velocity is 4374.45 m/s.
I got the answer by using v=d/t.
20,000meters / 25min= 4,374.45 m/s.
