(a) Three trains cars are connected and moving at a speed vo. A fourth car with speed 2vo catches the group and connects to them, to make a group of four. All four then collide with a fifth car that was at rest. The five cars now all move together. Assuming all the cars have identical mass, what is the speed of the entire group coupled together?
