Tennis Training Balls
if you stand in front of a slow moving train and throw a tennis ball?
if you stand in front of a slow moving train and throw a tennis ball head on at it, the ball will bounce back towards you.... this means that at some point in time, the ball will have to be stopped in relation to the ground at the same time as it's in contact with the train....so has the ball stopped the train or is it the wrong sort of leaves on the track...(something to do with squareroot of minus one probably)
This is a classic fake-logic question. The answer is no, if you plot the velocity of the ball, you see that it slows down, stops (for a moment) and changes direction. The fake logic says that if the tennis ball isn't moving then neither is the train (I think because of conservation of energy). But you must consider the TOTAL energy of both the tennis ball and the train and this will not change, I think because if you plot it as velocity then this of course is directional, but the total energy is calculated from the speed, which is not directional and this total will be conserved.
In reality the ball is not rigid and you would also lose some energy as heat from the friction of the impact and the compression and subsequent expansion of the rubber. I think this cropped up in my 'A' level physics lectures.
