There is an issue I have been puzzling over for some time now, without success. True it’s not going to change the world but then, what does? That’s not the question by the way! The problem is, a bee flying West collides with a train heading East. The bee is travelling at 3 mph and hitting the train will decrease that very rapidly. It then moves to travelling at 80 mph in the opposite direction (the speed of the train) - since it is now glued firmly to the front of the train. Now in moving from 3 mph West to 80 mph East at some point (when it hits the train) it’s speed has to hit 0 mph i.e. for the briefest period of time it is stationary. So here’s the problem – you have two bodies, connected to each other, one of which is stationary and the other is moving at 80 mph? This strikes me as somewhat illogical.

By the way, no bees were hurt in the making of this question.
