Assuming that Superman has unlimited strength and superfast legs, what 
would be his maximum running speed with a pair of regular Nike's.  I 
assume that there would have to be a maximum because there is only so 
much friction between his shoes and the ground, and if he pushed too 
fast, inertia would have him fall flat to the ground.  Also, as a person 
runs faster, they have to hop higher and higher off the ground and they 
can only fall so fast back to the ground.  There has to be a delay 
between each step.  Any rudimentary guesses would be appreciated, and 
show equations and stuff if you have them.  Thanks.
