Question
At what rate would a 75kg person travel during a slip/fall on a wet surface to the landing position? And what would be the force of the fall?

More info is needed for an accurate answer.
What matters is the person's height and weight distribution. A 75 kg person will have height about 1.8 m with a center of mass at H = 0.9 m.
The speed when he or she hits the ground will be about sqrt(2gH)= 4 m/s
The force of the fall will depend upon the type of clothing worn. Clothes exert a "cushioning" effect.
An approximate impact IMPULSE could be calculated from momentum principles.

Person is 5'3-1/4." Light clothing, no cushioning effect.
thanks!

For impulse, use mass*approximatevelocity
