Question
**Physics Problem: Collision and Velocity** A toy train engine (3.4 kg) is moving 0.25 m/s to the right when it collides with a train car (3.9 kg) moving 0.15 m/s in the opposite direction, and they stick together. Find the velocity of the engine-car combination as they move off together. Assume "to the right" is the positive direction. **Options:** A. 0.04319 m/s B. 0.05252 m/s C. 0.0687 m/s D. 0.04904 m/s E. 0.03505 m/s F. 0.0363 m/s --- Please solve the problem by applying the principles of conservation of momentum.
