You failed to take into account that the pin arrives at a speed and exits at the same speed but in the opposite direction. If the pin arrives in the hand at 70km/h and is accelerated in the opposite direction and leaves the hand at 70km/h, then you have a differential speed of 140km/h, but only a throwing speed of 70km/h, which is reasonable.
-70 +140 = +70
I would imagine the pin would be in the hand for a shorter period than this, and I only used 1 second in the hand as an example because it made the underlying math more easy to understand.
An
exact acceleration equivalent to 4G's (upwards) is the only acceleration acceptible and possible for the juggler to juggle 5 pins with a smooth motion.
