this is a fairly subtle question. if the bike was simply a 10kg object moving at 10m/s, then the KE would be KE = 0.5*m*v^2 = 0.5*(10kg)*(10m/s)^2 = 500 J but there is also rotational KE in the motion of the tires, which depends on their moment of inertia and radius. but as you didn't...

Ångström a unit of distance equal to 10^(-10) m cheers

"quantum theory and relativity both depend on "observers" " no - they don't. the rest of your post is philosophy/metaphysics... so, you should probably post those parts in the philosophy forum... good luck!
