comment Successive Bounces of Ball Paradox
Could it be resolved if the balls height is assumed to be fixed for all bounces?

Thanks Sam, your answer appears to have resolved the apparent paradox.

comment Successive Bounces of Ball Paradox
My argument for method 2 is like this. Let's assume velocity is 2m/s. Distance = 2*t. After 3 seconds, Distance = 2*3 = 6m, exceeding 2.

comment Successive Bounces of Ball Paradox
Argument for Method 2: Speed = Distance/time. Distance = Speed*Time. Speed is constant. There is no upper bound on time, and therefore no upper bound on distance.

Ok thanks guys these comments have been useful.

Isn't it discontinuous because the limit as f(x) approaches 0 is not equal to f(0)?
