A railroad flatcar is traveling at the speed of 13.0 m/s relative to an observer standing on the ground. Someone is riding a motor scooter on the flatcar. What is the velocity(magnitude and direction)of the motor scooter relative to the flatcar if its velocity relative to the observer on the ground is
a) 8.0 m/s to the right?
b) 2.0 m/s to the left?
c) zero?

    What is the direction of flatcar motion? You need to say what it is.

    (c) If the scooter has has zero
    velocity relative to the ground, it is going
    at the flatcar velocity but in the opposite direction, relative to the flatcar.
