Q: Suppose the speed of light were 100 mph. Trains on parallel tracks are approaching each other at speeds of 92.64 mph and 87.89 mph. A person on one of the trains sees the two trains approaching each other at what speed?
After the trains pass a crazy person on the 92.64 mph train fires a rifle with muzzle velocity 92.64 mph back at the other train. With what speed does the person on that train see the bullet approach?
