14,200 kg railroad cart that is traveling at a speed of 24.0 m/s collides with a 11,500 kg cart that is at rest. If the two carts lock together as a result of the collision, then what is their speed just afterward? If the second cart (in question 7) had been moving at 14.0 m/s (in the same direction as the first) before the collision, then what would be their speed just after the collision if they lock together?
