    Fly hitting a train physics problem

    but surely it changes direction, so at some point it must be traveling at 0mph? It goes from traveling at 5mph West and then when it hits the train it is traveling 100mph East, so there must be a crossover point when it is neither traveling East or West and is therefore traveling at 0mph?

    Fly hitting a train physics problem

    If a train is traveling 100mph in one direction and a fly is traveling 5mph the opposite, and the fly hits the train what speed is the fly traveling at the point of impact?
