Why can't humans run 100 mph?

Answer 1

First of all there are no animals that can do that. The fastest is the cheetah and it can get up to 70-75 mph in short bursts less than a quarter mile long.

Though there may be some confusion about evolution as being a factor in why certain animals develop specific traits that are different than other animals, it does not imply that given enough time, humans could evolve into faster runners, especially not approaching 100 mph.

From a biomechanical perspective, we were not designed to run that fast, so we do not have the body structures that can generate the required amount of force to propel us to 100 mph. The fastest humans can only get up to 20 mph in short sprints of about 100 yards.

We were designed to use our minds and our hands for intricate and complex manipulations of small objects; tools.

Weight and Aerodynamics. The basic principles involved are leverage and the Second Law of Physic by Issac Newton that has to do with F=ma. There is just not possible to generate a Force in the human body that comes even close to approaching Mass x Acceleration to propel it to 100 mph.
