A railroad car of mass 3.45 x 104 kg is traveling east at 5.50 m/s and collides with a railroad car of mass 4.21 x 104 kg traveling west 1.50 m/s. Find the velocity (in m/s) of the railroad cars that become coupled after the collision. Assume east is the positive direction
Assuming east as the positive x-direction
The initial momentum of the system is
Now, when both the cars get coupled after the collision, the momentum of the system is
Applying conservation of momentum
So, after the collision, the cars move to the east with a velocity of 1.65 m/s.
