A 12,000 kg railroad car, initially traveling at 1.6 m/s, strikes three identical and connected railroad cars, initially at rest. The track is horizontal and frictionless. After the collision, all four cars move together at the same velocity. A.) Determine the final speed of the cars. (0.4 m/s). B.) Assuming the collision took 1.5 seconds, calculate the average force of collision. C.) How much non-conservative work was done during the collision? (-11500 J)

A railroad freight car weighing 28000 kg and traveling at 6.0 m/s overtakes one weighing 19000 kg and traveling at 4.0 m/s in the same direction. If the cars couple together, find (a) the speed of the cars after collision and (b) the loss of kinetic energy during collision. (c) Is this collision elastic or inelastic? Please explain the steps. Thank you!
