Transcribed Image Text:Part A
A railroad flatcar is traveling to the right at a speed of 13.0 m/s relative to an observer standing on the ground. Someone is riding
a motor scooter on the flatcar (Figure 1).
What is the magnitude of the velocity of the motor scooter relative to the flatcar if its velocity relative to the observer on the ground is 18.0 m/s to the right?
