hey could someone tell me how to start this problem? i dont know which formula i'm suppose to use.. A 90 m long train begins uniform acceleration from rest. The front of the train has a speed of 19 m/s when it passes a railway worker who is standing 190 m from where the front of the train started. What will be the speed of the last car as it passes the worker? is the velocity 19 m/s? and the distance is 190 m?
