Two cars with a mass of 1 ton are moving in the same direction: one at a speed of 25 m / s, the other at a speed of 20

Two cars with a mass of 1 ton are moving in the same direction: one at a speed of 25 m / s, the other at a speed of 20 m / s relative to the ground. What are the impulses of cars in the ground reference frame? What is the momentum of the first car in the frame of reference associated with the second car? What is the momentum of the second car in the frame of reference associated with the first car?

Decision:
p1 = 2P * 1000 = 20,000 kg * m / s
p2 = 25 * 1000 = 25,000 kg * m / s
рЗ = 1000 (25 – 20) = 500 0 kg * m / s
p4 = 1000 (20 – 25) = – 5000 kg * m / s
Answer: 20,000 kg * m / s; 25,000 kg * m / s; 5000 kg * m / s; – 5000 kg * m / s
