A 2.00×104 kg railroad car is rolling at 6.00 m/s when a 7000 kg load of gravel is suddenly dropped in. What is the car's speed just after the gravel is loaded?
-Please show how you do each step, I really want to learn how to understand this if you have the time to. Thank you.

A railroad car of mass 3.10 ✕ 104 kg moving at 3.40 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.20 m/s. (a) What is the speed of the three coupled cars after the collision? (b) How much kinetic energy is lost in the collision?
A railroad car of mass 3.15 ✕ 104 kg moving at 2.75 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.20 m/s. (a) What is the speed of the three coupled cars after the collision? (b) How much kinetic energy is lost in the collision?

A railroad hopper car filled with sand is rolling with an initial speed of 15 m/s on straight, horizontal tracks. You can ignore frictional forces on the railroad car. The total mass of the car plus sand is 85,000 kg. The hopper door is not fully closed so sand leaks out the bottoms. After 10 minutes, 13,000 kg of sand has leaked out. So I thought that because it does not say that it is elastic or inelastic that I...
