Muy bueno!!! Gracias Mike por el aviso!
What would happen? [I haven't looked at the solution anywhere] Wouldn't the ball get heavier and heavier until it reached 90% of c, at which point it would be almost infinitely heavy and, therefore demand almost infinite energy just to move it? Now, if it were to reach c, then it would be infinitely heavy and require an infinite amount of energy to move it. Or it would have become a bunch of rays and particles that behave rather capriciously (sometimes rays, sometimes particles) and that we call light, in a package of photons. That is according to Einstenian physics, if I remember well, which doesn't explain a lot of stuff and makes it impossible (or so Einstein thought) for us to ever travel at the speed of light (c) or FTL, which would be really cool. Since Einstein never cared much for quantum physics ("God doesn't play dice") it is, at least theoretically possible to imagine a scientific way to reach c or FTL because Einstein did not include quantum concepts into his theoretical physics.

Check the site, Sergio. In the question, the ball leaves the pitcher's hand already at 0.9 c

Good for Him. I play craps. And hardball.
Oh, you like hypothetical questions? Well, I DON'T. Here's a straight-up Q for you: why do I feel this urge to bully people right now? Try and answer it with physics. By next Tuesday.
