A very long train is rolling at 4 m/s along a straight track. An observer is standing on the ground very dangerously close to the train as moves past notices a person standing on top of a car. When the person on the car is 300 m from the observer, the person begins running toward the observer at 6 m/s. A. Please write down the velocity vector equation for the person with respect to the ground.
B. How much time does the person take to reach the observer?
