What is the momentum of a two-particle sys- tem composed of a 1300 kg car moving east at 100 m/s and a second 1300 kg car mov- ing west at 35 m/s? Let east be the positive direction.

Answer in units of kg · m/s

To find the momentum of a two-particle system, you need to calculate the total momentum of each particle and then add them together.

The momentum of an object is given by the formula: momentum = mass x velocity.

For the first car, which is moving east at 100 m/s, the momentum can be calculated as:
momentum_1 = mass_1 x velocity_1 = 1300 kg x 100 m/s

For the second car, which is moving west at 35 m/s, the momentum can be calculated as:
momentum_2 = mass_2 x velocity_2 = 1300 kg x (-35 m/s) [since moving west is considered negative]

Now, to find the total momentum of the system, we need to add the individual momenta:
total momentum = momentum_1 + momentum_2

Substituting the values:
total momentum = (1300 kg x 100 m/s) + (1300 kg x (-35 m/s))

Now, you can perform the arithmetic to find the numerical value of the total momentum.
