wrong, the speed of light is approximately 299 792 458 meters/second in a vacuum, not 324 meters/second in a vacuum
Answer:
Agree
Explanation:
Distance is described as "how much ground an object is covered" in physics, and because the object is moving, no matter which direction, it is constantly gaining more distance. You can think of the object as a car, and as the car is moving down a highway it is gaining more and more distance as the seconds go by.
You might be confused with the term displacement, "how far out of place an object is" which in this case would be false.
Does that make sense?
Answer:
Let the momentum of the orange train be positive
P = 100 * 8 - 200 * 1 = 600 kg-m/s
P(final) = 600 kg-m/s
P / M = 600 kg-m/sec / 300 kg = 2 m/s
Answer-B final momentum = 600 kg-m/s
