Asked Aug 27, 2019

a 75-m-long train begins uniform acceleration from rest. The front of the train has a speed of 18 m/s when it passes a railway worker who is standing 180 m from where the front of the train started. what will be the speed of the last car as it passes the worker?

Step 1

Use equation of motion to find the uniform acceleration of the train. The initial velocity of the train is zero.

Step 2

The time required for the last ...
