This is all under the assumption that they are perfectly rigid bodies:
A train is moving at 300m/s. A mosquito is moving directly towards it, head-on, at 4m/s.
When the mosquito and the train collide, the mosquito is at 0m/s, and then changes direction, moving at 300m/s in the direction of the train (because it's stuck to the windscreen).
Surely this says that, in theory, because there is a period of time where the mosquito is at 0m/s, the train must also be at 0m/s. But the train surely doesn't stop moving, and a mosquito certainly couldn't stop a train, even for the smallest amount of time.
- Is this really what theory predicts? If not, where am I going wrong?
- Is the theory flawed with this almost paradoxical situation?
