A railroad handcar is moving along straight, frictionless tracks with negligible air resistance. In the following cases, the car initially has a total mass (car and contents) of 190 kg and is traveling east with a velocity of magnitude 5.30 m/s. Find the final velocity of the car in each case, assuming that the handcar does not leave the tracks.
An object with a mass of 25.0 kgkg is thrown sideways out of the car with a speed of 2.50 m/sm/s relative to the car's initial velocity.
Express your answer with the appropriate units.
An object with a mass of 25.0 kg is thrown backward out of the car with a velocity of 5.30 m/sm/s relative to the initial motion of the car.
Express your answer with the appropriate units.
An object with a mass of 25.0 kg is thrown into the car with a velocity of 6.00 m/sm/s relative to the ground and opposite in direction to the initial velocity of the car.
Express your answer with the appropriate units.

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...

Two railway cars are on a straight railroad track. The first, with mass 8000 kg, moves slowly at a velocity of 0.05 m/s to the right in the direction of the second car of mass 15000 kg, which is stationary. (a) What is the total momentum (relative to the ground) of both cars together? kg m/s They collide and stick to each other. What is the total momentum right after the collision? For the short times involved, you can take...
